电动负载模拟系统自适应控制系统设计
Design of adaptive control system of electric load simulation system
摘要
Abstract
In order to eliminate the redundant moment of force of the electric load simulation system (ELSS) and improve the output accuracy of the system loading torque, a kind of adaptive control method for eliminating position disturbance torque of steering engine was designed.Based on the feed forward control and adaptive control theory, the effectiveness of the method was analyzed by MATLAB simulation software and the experimental verification was carried out.Simulations and experimental results showed that the method could adaptively adjust the system loading error, and the higher the frequency of the steering engine was, the longer the tracking error could be adjusted.In the same conditions of the loading torque and amplitude phase of the steering engine, the higher the steering engine frequency was, the more obvious the inhibitory effect of the control method to the redundant moment of force was.In the same conditions of the loading torque and movement frequency of the steering engine, the greater the amplitude phase of steering engine was, the more obvious the inhibitory effect was.The method can stabilize the system in an ideal output state by the output of the reference model when the actual system parameters are unknown or gradually changing.The research results have certain reference values for the design of aircraft electric load simulator.关键词
