Simulation of a digitally controlled system, using the SIMUL language: design of an anti-reset windup integral and state feedback controller

The SIMUL simulation language is introduced and its application to the simulation of continuous-time systems controlled by digital computers is described. Then, the control of the primary coolant temperature in a PWR nuclear power plant is considered. Large disturbances induce unacceptable transient oscillations due to the actuator speed limits; it is shown that these oscillations can be damped or eliminated, using a correction algorithm with a single parameter, the value of which can be determined via simulation.Anglai
