Lead-lag Controller: Recap and Feedforward Action

This lecture covers the lead-lag controller, explaining the lead and lag times in the controller form, the process control, and the feedforward controller for GL(S) and Gp(s). It also discusses the controller output to a unit step response, the step response of the lead-lag controller, and the amplitude and time characteristics. Additionally, it recaps the feedforward controller, the dynamical model, the feedback controller, disturbance rejection, and the example of a stirred tank heat exchanger with single feedback and feedback-feedforward controllers.
