Model Predictive Controlled Quasi Z Source Inverter Fed Induction Motor Drive System

Abstract

Ongoing advancements in inverters have offered pathway to high gain quasi Z source inverter Circuit (QZSIC).High gain QZSIC can be found between Semi Converter (SC) and three phase Induction Motor Loads (TPIML). This paper proposes suitable controller for closed loop controlled QZSIC-TPIML. This strive deals within improvement in time-response of QZSIC fed induction motor system. The objective of this effort tis to design a closed loop controlled QZSI*fed-induction motor framework that provides a stable-rotor-speed. The QZSIC is settled to switch it to "3phase AC". The yield of 3phase inverter is sieved before it"s applied to a"3phase-Induction-motor". Closed loop control of QZSIC-TPIML using SMC and MPC is simulated &their rejoinders are compared. The "Model Predictive controller (MPC)" is acclaimed to retain persistent significance of-speed. The result obtained via MP-controlled QZS-IIMDmethod is compared with Sliding mode-controlled SMC) QZS-IIMD systems for change in input voltage. The wished-for MP controlled-QZS-IIMD method has benefits like fast settling-time and less steady state speed error.PIC16F84basedhardware for 0.5HP, QZSIC-IMDS is implemented.
