Design of PI-lead controller for a plant having a right-half-plane zero

In engineering applications, DC-DC power supplies play a vital role. Such type of applications requires a regulated output voltage and a steady state operation irrespective of load changes. This is a challenging problem in boost converter which is of non-minimum phase type. Therefore, in this paper, a technique is proposed to design PI-Lead compensator for boost converter. The main advantage of this technique is that the desired performance can be achieved, particularly phase margin. Further, this approach is better in comparison to conventional PID controller and also recently published PI-Lead compensator design method.
