Performance estimation of stability and fault analysis for BLDC motor using PID tune ANN controller with state space model [articol]

Abstract

In this article, the steady state stability and internal fault analysis of the Brushless DC motor (BLDC) with Hybrid PID-ANN Controller has been analyzed with state space model. The steady state stability analysis of the proposed controller has been examined using state plan and Lyapunov Technique. The proposed controller performance is analyzed for sudden change in load, speed variation, Open circuit fault (OCF) and Short Circuit Fault (SCF) occur disturbance condition of the motor has been presented and also the controller performance is compared with conventional controller. A prototype model 300W, 50Hz system is developed and built, the transient and dynamic performances for the BLDC motor are compared and presented. From the simulation and experimental results, it is found that the PID-ANN Controller can have better controller compared with conventional controller.
