Lecture

Cascade Control: Stability Limits and Offset Error Analysis

Description

This lecture covers the determination of stability limits for conventional proportional controllers and cascade control systems with two proportional controllers, as well as the calculation of offset error for a unit step change. It also discusses the properties of cascade control, including rapid rejection of perturbations, improved disturbance rejection, and enhanced stability margin, leading to reduced steady-state error.
