摘要
基于1/4汽车悬架为控制对象,建立了汽车悬架动力学模型.以线性二次型最优(LQG)控制和改进后的半主动开关(on-off)控制为控制策略,在MATLAB/Simulink软件平台上进行仿真.与被动悬架比较,采用正弦激励下的频域分析和随机路面激励下的时域分析,证明了LQG控制和半主动开关控制在汽车控制工程中的可行性.
Based on one-fourth vehicles as a control object,a vehicle suspension dynamic model was established.The simulation of the vehicle suspension was designed with Linear Quadratic Gaussian（LQG） and the modified semi-active（on-off） control strategy,carried out on MATLAB software platform,and compared with the passive suspension.Taking the analysis of the frequency domain under sine excitation and the time domain under random road excitation,the feasibility of the LQG control and semi-active on-off control in automobile control engineering was proved.
