履带车半主动悬架的复合控制策略研究
Study on Complex Control Strategy for Semi-active Suspension of Tracked Vehicles
摘要
Abstract
For the multiplicity,complexity of the driving traffic and its unique structure,an intelligent hybrid control method of tracked vehicle active suspension based on MR damper was proposed. Taking one half of the tracked vehicle suspension system as the research object, the vertical amplitude, pitch angle and vertical body acceleration response of the body were analyzed. This control method used the MR damper as an actuator, and a fuzzy control as feed forward and also PID control as feedback based on preview. The control system model was setup in MATLAB/Simulink, using the complex random road output to Simulink,the simulation results show that it has good real —time control ability,good robustness and high accuracy,etc. Contrast to passive suspension, the body vertical amplitude,pitch angle and the body vertical acceleration of the semi —active suspension system using the intelligent hybrid control method are well controlled,among them,the vertical amplitude RMS decreases by 37. 2%, the pitch angle RMS decreases by 45. 2%,the vertical vibration acceleration RMS decreases by 38. 6%.关键词
