Passivity-Based Control Strategies of Brushless Doubly-Fed Machine
摘要
Abstract
A novel passive control strategy was proposed to improve the dynamic response performance of the speed and load torque of the brushless doubly-fed machine( BDFM) with the nonlinear PID control scheme,and the oscillation as the load changes suddenly. The Euler-Lagrangian model of BDFM was established based on the equations of the voltage,flux and torque of BDFM in synchronous speed rotary coordinate system. The passivity of the electrical subsystems and mechanical subsystems of the machine were analysized by the view of energy, and the controllers of the torque and speed were designed. In order to improve the system dynamic response and reduce its sensitivity to parameter variations, the nonlinear damping was added into the controller to make the system achieve fast convergence. A novel simulation model of BDFM with passivity control strategy was built in MATLAB/Simulink environment. The simulation results showed that a given speed of BDFM could be fastly tracked, BDFM had good dynamic performance,global stability and good robustness with the passive control strategy.关键词
