Plant Models for Control System Design

Physics-based, Validated Plant Models for Simulation Testing

It can be challenging to derive a plant model that is of sufficient fidelity to be useful, capturing the non-linear effects and system dynamics that are important for control system design. In addition to the powerful Enginuity tool for engine controls development, SimuQuest has developed a number of other plant models (and corresponding algorithms). These plant and algorithm models, implemented in native Simulink, are commercially available and have saved clients a lot of valuable development time. SimuQuest plant models have been developed and validated against dynamic measurement data to achieve sufficient fidelity for comprehensive model-based design.

Vehicle Body Plant Models

Electrically powered vehicle body systems such as power windows, sliding doors and rear liftgates involve complex subsystems and non-linearities such as:

          • dc motors
          • end stops
          • compliant cables
          • pulley slippage
          • hydraulic mechanisms
          • gear mechanisms
Cable Driven Power Window

PwrWindowCableType2

This plant model captures the complex non-linear effects of the cable and pulley and end stops, that are critical to the correct implementation of the anti-pinch algorithm and other control features.

Cross Lever Power Window

748-938

This plant model captures the complex non-linear effects of the cross lever, gearing and end stops, that are critical to the correct implementation of the anti-pinch algorithm and other control features.

Power Liftgate

Liftgate1Captures the complex non-linear effects of the pneumatic dampers, latching mechanism, complex geometry and end stops, that are critical to enable correct implementation and simulation testing of the control features.

Power Sliding Door

SlidingDoor2

Captures the complex non-linear effects of the cable, pulleys and end stops, that are critical to the correct implementation the control features.

Powertrain Plant Models

Powertrain plant models include vehicle, engine, driveline, hybrid vehicle and electric vehicle models, incorporating the dynamics and non-linear effects that are important to control system design.
