摘要
Abstract
The brushless DC motor in electro hydraulic actuator (EHA) was required to start and brake frequently,having a relatively fast dynamic response.One-cycle control method was employed in EHA brushless DC motors due to the disadvantages of the common PID control method in non-linear systems.The one-cycle controller was used to control the torque output of motors in order to improve the capability of resisting disturbance and enhance dynamic performance.Common PI controller was employed to accomplish the control of system position and rotate speed,making system structure simple and easy to realize.Simulation results showed that,after introducing one-cycle control method in current loop,the system had a better performance in stability and the fluctuation of the motor rotate speed and torque was smaller in steady state.An experiment was conducted on a platform including 28 kW angle power EHA and a digital controller based on "FPGA+DSP" structure,whose results verified that the EHA system based on the one-cycle control method had a excellent performance both in steady-state and dynamics.关键词
