Lead Compensator Design

This lecture covers the design of lead compensators, focusing on the Phase Lead Compensator. The lead compensator is designed to increase phase and slope near the crossover frequency, improving system stability. The lecture explains the utility of lead compensators, the criteria for choosing lead ratio 'a', and the impact on phase margin and crossover frequency. Examples illustrate how to design lead compensators to meet specific requirements, such as reducing steady-state error and overshoot. The lecture also discusses the design procedure, including selecting the controller gain 'K' and determining the increase in phase margin required for stability.
