汽车防抱制动系统的分数阶PID控制算法研究

Research on Fractional Order PID Control Algorithm of Anti-locking Braking System of Automobile

鉴于汽车防抱制动系统控制过程中存在时变性、非线性、不确定性等问题,采用一种基于分数阶PID的控制方法,设计了分数阶PID控制器,并在Matlab/Simulink系统进行了单轮车辆的防抱死制动仿真;仿真结果表明:该控制策略具有更好的鲁棒性,控制效果更优。

According to the time-varying,nonlinear and uncertain problems and so on in the process of antilocking braking system control of automobile,this paper uses a kind of control methods based on fractional order PID to design fractional order PID controller,and makes anti-blocking braking simulation for single tire automobile in Matlab /Simulink system. The simulation results indicate that this control strategy has better robustness and has better controlling effect.
