摘要
设计一款基于6-RSS并联机器平台的新型小球系统,先对6-RSS并联机器平台进行逆运动学求解,得出控制平台旋转舵机所需转动的角度,再采用4线电阻屏采集小球在平板上的位置,对小球系统利用拉格朗日函数进行数学模型求解,提出LQR控制器模型,最终对控制器进行Simulink仿真,得到在阶跃响应下小球位置和平板转角的响应曲线。
Design a new ball system based on the 6-RSS parallel machine platform.First,solve the inverse kinematics of the 6-RSS parallel machine platform to obtain the rotation angle required to control the platform’s rotating steering gear.A 4-wire resistive screen was used to collect the position of the ball on the plate,and the mathematical model of the ball system was solved by using Lagrangian functions,and the LQR controller model was proposed.Simulink simulation of the controller was performed to obtain the ball position under the step response.And the response curve of the plate corner.
