Fuzzy PID Controller for Z-source Inverter

Fuzzy PID controller is used to control the duty cycle of shoot-through mode in a Z-source inverter (ZSI). To model ZSI, its small signal model is employed. Moreover the inverter part is presented by a single switch in shoot-through mode.It is shown that the PID controller has an effective impact on the performance of ZSI. In addition others parameters such as settling time is reduced considerably
