摘要
为了满足人们对新能源汽车舒适性和安全性的双重要求,防夹技术广泛应用于电动车窗系统中。针对防夹系统的不稳定性和响应慢的问题,提出了一种霍尔脉冲计数与滑模控制相结合的防夹控制算法,将高阶非线性系统拆解成若干个低阶子系统,利用Lyapunov函数来判别子系统的稳定性,并搭建了基于dsPACE核心控制板DS1103的电动车窗防夹实验平台,通过该实验平台对采取的防夹算法进行验证。实验结果表明,该防夹控制算法响应速度快且具有很强的适应性和防夹能力。
In order to meet people′s dual requirements for the comfort and safety of new energy vehicles,anti-pinch technology is widely used in electric window systems.Aiming at the instability and slow response of the anti-pinch system,an anti-pinch control algorithm combining Hall pulse counting and sliding mode control is proposed to disassemble the high-order nonlinear system into several low-order subsystems.The Lyapunov function is used to judge the stability of the subsystem,and the electric window anti-pinch experiment platform based on dsPACE control board DS1103 is built.The anti-pinch algorithm is verified by the experimental platform.The experimental results show that the anti-pinch control The algorithm is fast in response and has strong adaptability and anti-trapping ability.
