运用ADAMS软件建立车辆动力学模型,进行动力学仿真运算。将由此得到的仿真结果传给MAT LAB软件,由MATLAB软件编写开关控制算法,计算出横向最优阻尼并将其值传给车辆模型。通过改变车辆模型中的横向阻尼值再次进行仿真运算,将运算结果再次传给MATLAB软件。如此相互调用,循环计算,从而找出最佳匹配阻尼值。在DSP硬件平台上编写横向半主动控制算法,使逐步寻优和开关控制相结合,以实现最优阻尼的开关控制。经使用标准信号和实车随机信号对算法进行仿真验证表明,这种控制算法简单可靠,能够实现对车辆横向的半主动控制策略。
Using ADAMS software to establish the vehicle dynamics model for dynamic simulation. The resulting simulation results are passed to MAT LAB software and the switch control algorithm is programmed by MATLAB software to calculate the lateral optimal damping and pass the value to the vehicle model. The simulation results were changed again by changing the lateral damping in the vehicle model and the results were again passed to the MATLAB software. So call each other, loop calculation, in order to find the best match damping value. In the DSP hardware platform to write horizontal semi-active control algorithm, so that the gradual optimization and switching control combined to achieve the optimal damping switch control. The simulation results show that the proposed control algorithm is simple and reliable, and can realize the semi-active control strategy for the transverse vehicle.
