Full-model SDRE
Recompute the state-dependent control law against the commissioned nonlinear model under the declared update deadline.
Controller
Full-model control from measured dynamics
Use real-time SDRE when the update cadence is strict and full-model NMPC where a slower optimisation loop is acceptable. The self-service product returns bounded supervisory recommendations; the operator, PLC or supervisory application remains responsible for execution.
Controller can be ordered independently or used alongside Filtration & analytics. Full Filtration, Analytics, Passports and NDC compiles remain separate products.
Full-model NMPC
Use the full offline model and constrained horizon optimisation when the workflow does not require the strict SDRE cadence.
Advisory output
Commands remain bounded and status-bearing; execution authority and interlocks remain outside the self-service product.
Fast decision
Use Controller for a live system with explicit limits
The Controller can be used as a standalone supervisory product or combined with Filtration & analytics. It is advisory by default and does not silently take command authority.
- Best for
- A live civil or scientific system that needs bounded next-action recommendations.
- You provide
- Synchronized measurements, applied commands, operating limits and a declared update cadence.
- You receive
- A bounded recommendation with status, constraints and explicit operating-boundary information.
- Buying model
- Standalone or added to a live-stream configuration. The current input-review page checks stream health and numeric bounds; it does not establish controller readiness or provide a price quote.
Review Controller inputsReview the workflowNo separate Analytics subscription is required. Unsupported configurations must be rejected before purchase rather than handled through a sales conversation.
What it does
Move from the current state to a constrained next action
The Controller focuses on the decision that must be made now: which bounded command is appropriate under the measurements, applied command, objective and limits supplied to the controller.
Calculate the next recommendation
Return a command or setpoint recommendation from the latest control-ready state.
Respect the operating envelope
Apply declared command bounds, maximum command change and controller horizon.
Expose readiness and degradation
Report when the controller is ready and when the result is degraded instead of hiding that state.
Workflow
Connect, constrain, advise
The product has a short, repeatable operating path. It does not require the customer to buy the separate Analytics surface.
01 · CONNECT
Send a control-ready stream
Provide synchronized measurements, the actual applied command and any contextual drives required by the selected controller mode.
02 · CONSTRAIN
Declare objectives and limits
Set command bounds, maximum change, horizon and the applicable state or control weights.
03 · ADVISE
Receive a bounded result
Get readiness, controller mode, recommended command and any degraded-state reason. A stop/disarm path remains available.
Inputs and outputs
A clear control contract for integration
The integration separates what the controller needs from what the surrounding plant or application must continue to own.
Live measurements
Time-aligned numeric state or output measurements from the system being supervised.
Applied command
The command actually applied to the system, so the controller reasons from the real control history rather than an assumed one.
Limits and tuning
Command minimum and maximum, maximum step, horizon and supported objective or weighting parameters.
Recommendation
A bounded command or setpoint result together with readiness, mode and degraded-state information.
Execution boundary
The operator, PLC or supervisory application decides whether and how to apply the result and retains physical interlocks.
Applications
Useful wherever a live system needs disciplined setpoint decisions
Controller is designed for civil engineering systems where measurements and applied commands are available and operating limits can be stated explicitly.
TEST RIGS
Supervisory test operation
Recommend actuator or setpoint changes while a test controller and physical interlocks remain in charge.
THERMAL & PROCESS
Bounded process recommendations
Use measured temperature, pressure, flow or other process state under declared command limits.
ENERGY & HVAC
Operating-point guidance
Calculate constrained recommendations for systems with delayed response and changing demand.
LAB EQUIPMENT
Repeatable supervisory decisions
Keep recommendation logic consistent across repeated runs while recording readiness and degraded states.
How it combines
Use Controller alone or add visibility around it
Controller remains the same controller product in every configuration. Other products add their own results rather than being silently bundled into Control.
STANDALONE
Controller only
Connect the required live stream and use the control recommendation, readiness and degraded-state outputs.
+ SIGNAL
Add customer-facing filtration
Buy Filtration & analytics separately when you also need cleaned stream outputs, gap recovery or the three filtration modes.
+ ANALYTICS
Add diagnostic evidence
Buy Analytics or Team separately when you also need events, channel health, predictive dependencies and a System Passport.
Operating boundary
Advisory by default, with explicit limits and status
The self-service product recommends; it does not silently take command authority over physical equipment.
Bounds
Command minimum and maximum are declared for the request.
Rate limit
Maximum command change can be constrained.
State
Readiness and degraded conditions are returned with the result.
Disarm
A dedicated stop/disarm path is retained.
Autonomous actuation is a separate restricted capability requiring its own authorization and commissioning. It is not included in the ordinary self-service Controller product.
Engineering evidence
Qualification is tied to a declared benchmark protocol
The current table reports simulation evidence for the implemented controller family. It is not a field-performance guarantee for an unqualified installation.
| Controller family | Mean normalized score ↓ | Role in the protocol |
|---|---|---|
| Automatic B1 full-model SDRE | 0.434471 | Deployable causal selector in the declared test |
| True frozen linear LQR | 0.761707 | Future-selected diagnostic comparator |
Real installations remain responsible for sensors, actuators, physical interlocks, operating limits and acceptance testing.
FAQ
Questions about Controller
Can I buy Controller without a Filtration & analytics subscription?
Yes. Controller is intended to be available as a standalone product with the live-stream functions required for its own operation.
Does Controller include full Filtration or Analytics?
No. It includes only the internal processing required to calculate the recommendation. Customer-facing filtration modes, Analytics reports, Passports and NDC compiles are separate products.
Does NLSYS apply commands directly to my equipment?
The self-service product returns recommendations in shadow or advisory operation. Your operator, PLC or supervisory application owns execution and physical interlocks.
What does the controller need?
Synchronized measurements, the actual applied command, the required contextual drives, and explicit command or setpoint limits for the selected mode.
What happens when the controller is not ready?
The response exposes readiness and a degraded-state reason instead of presenting an ordinary recommendation as fully qualified.
Is autonomous operation included?
No. Autonomous actuation is a separate restricted capability with its own authorization and commissioning requirements.
