Analysis of PID Control for Microprocessor-based Current Source Inverter-Induction Motor System

마이크로프로세서에 의한 전류형 인버어터 - 유도전동기의 PID제어시스템에 대한 해석

This paper is concerned with the analysis of microprocessor-based PID control for the current source inverter-induction motor derive system. A linearized dynamic model of the motor is derived and is converted into the discrete-time model. With the equation, the overall system including the feedback loops is formulated into a single discrete-time state equation. The stability regions are determined at various values of controller gains. The transient responses of the motor speed are simulated by digital computer and are verified by laboratory experiments.
