| Abstract |
An optimized digital PID controller for a single phase PFC converter is
proposed in this paper. With the help of
GENETIC ALGORITHM searching mechanism, the parameters of digital PID compensator are selected and optimized based on time domain
specifications such as response time, percent of overshoot etc. for a step reference. The phase margin of the feedback loop is checked to ensure
the stability of the system controlled by this optimized PID controller. The simulation shows excellent results in terms of response time and output overshoot for a step reference. This design approach provides an attractive alternative way to classical frequency domain methods to design a digital PID controller of the PFC converter. It can be easily extended to applications for all
switching regulator control loop design. |
