Design and implement a gain-scheduled PID controller for a continuous-stirred tank reactor using Simulink Control Design™. Gain scheduling is used for controlling plants that have dynamics varying from one operating condition to another. This video details the workflow for designing and implementing a gain-scheduled PID controller. A plant model in Simulink^® is automatically linearized at different operating conditions. PID controller gains are automatically tuned, and a gain-scheduled PID controller is implemented in Simulink using the PID Controller block and look-up tables.
