基于EUKF模型的PMSG系统无速度传感器控制
Sensorless Speed Control of PMSG Based on EUKF
摘要
Abstract
Considering the resistance perturbation of the permanent synchronous magnetic generator(PMSG) sensorlss speed controlled system,a novel passivity-based control based on extended unscented Kalman filtering (EUKF)and port-controlled Hamilton(PCH)model was proposed. Firstly,a PMSG system model with resistance perturbation was established,and the control law was designed by using PCH passive control theory to achieve maximum wind energy capture.Then,the system model was transformed into expanded unscented Kalman filte(r EUKF) model consisting of the system state and the stator resistance perturbation parameter. A nonlinear filter based on EUKF was designed to estimate the rotor speed and perturbation parameter simultaneously,the estimation results were transmitted to the controller in real time. Finally,the EUKF has better robust ability than traditional unscented Kalman filtering UKF for the PMSG system which is explored through system simulation with Matlab.关键词
