摘要/Abstract

摘要：

为改善汽车的平顺性和操纵稳定性，建立了包含主动悬架与主动横向稳定杆的整车动力学模型，并根据主动悬架与主动横向稳定杆两个系统间的耦合关系，分别设计了主动悬架与主动横向稳定杆的子控制器，将PID与线性控制相结合，设计了PID集成控制策略。在MATLAB/Simulink中对汽车的转向工况进行了仿真。仿真结果表明,PID集成控制策略有效,可提高车辆的操纵稳定性和平顺性。

关键词: 主动悬架, 主动横向稳定杆, 集成控制, PID控制

Abstract:

A dynamics model of a full vehicle which equipped the active suspension system and active roll stabilizer was set up to improve ride performance and handling stability of the vehicle. Also active suspension and active roll stabilizer controllers were designed based on the coupling relationship between the two systems. The PID integrated control strategy was designed based on PID control and linear control. The vehicle in the steering working situation was simulated with MATLAB/Simulink. The simulation results show the effectiveness of proposed integrated control strategy to improve handling stability and ride comfort.

Key words: active suspension system, active roll stabilizer, integrated control, PID control
