摘要

提出了一种基于电磁直线执行器的电子凸轮,通过对给定轨迹的跟踪来实现所需要的直线运动规律,以取代传统的机械凸轮机构。采用迭代学习控制算法控制电子凸轮实现对目标轨迹的跟踪,并进而应用迭代加模糊滑模控制的算法提高电子凸轮的收敛速度与鲁棒性。模糊滑模迭代控制是将误差函数输入滑模控制器中,然后以滑模函数作为模糊控制器的输入,最后通过模糊控制器的输出来控制迭代算法中的增量。通过仿真以及试验验证表明,基于电磁直线执行器的电子凸轮能够有效取代传统的机械凸轮机构,模糊滑模迭代控制算法能够满足电子凸轮对轨迹跟踪精度、响应速度、收敛速度与鲁棒性的要求。

Abstract

An electronic cam based on the electromagnetic linear actuator is proposed,by tracking the given trajectory to realize the required linear motion law and substitute the traditional cam mechanism. The electric cam is controlled by the iterative learning control algorithm to realize the track of the target trajectory. Moreover,the adoption of both iterative learning control algorithm and fuzzy sliding mode control can effectively improve the convergence speed and robustness of the electric cam. The fuzzy sliding mode iterative control is inputting the error function in sliding mode controller,which takes the function of a sliding mode control as the input of fuzzy control and takes the fuzzy control output as the control increment of iterative learning control. The simulation and the experiment shows that electronic cam based on the electromagnetic linear actuator can effectively substitute traditional cam mechanism,and the fuzzy sliding mode iterative control algorithm can satisfy the requirements of the precision of trajectory tracking,response speed,convergence speed and robustness of electronic cam.
