摘要
传统的四通道双边控制方法需要大量的力传感器,用以检测遥操作系统受到的环境力,在实际工程中不易推广应用.本文提出了一种无环境力反馈的四通道双边控制策略,分析了无时延和有时延两种情况下遥操作系统的透明性.并采用无源的双边控制律,设计了大时延情形下的系统控制结构.仿真结果表明,存在大时延时,提出的控制系统在自由运动和接触运动中都具有良好的性能.
In the project of traditional four-channel bilateral remote control systems, there needs a great number of force sensors for measuring the environmental forces. This requirement prevents the project from widely accepted in applications. In this paper, a strategy of four-channel bilateral control without environmental force feedback is proposed; and the transparencies of the remote control with or without time-delays are investigated in details. Furthermore, the stable control configuration in the presence of large time-delay is proposed according to passive bilateral control law. Simulations validate the performance of the proposed control system in free motion and contact motion.
