Abstract:
In order to ensure safety in the process of interaction between people and the manipulator and acquire the fast response without overshoot, the traditional PID control was improved by introducing the prescribed performance control, and a fast humanoid motion control algorithm without overshoot for the manipulator was proposed. Based on PID control, the algorithm utilizes the prescribed performance control to make the convergence speed and overshoot of control errors satisfy the preset conditions, and make the control error converge to a preset relatively small area, so as to control the steady and dynamic performance of the system (including overshoot and convergence speed, etc.).The analysis results of modeling and simulation of spatial three joints manipulator show that the proposed prescribed performance PID control has the advantage of fast response and no overshoot comparing with the traditional PID control. Thus, the control algorithm suits to anthropomorphic manipulator motion control. Finally, the validity of the algorithm was verified by the prototype experiment of Dobot robot with 4 degrees of freedom. © 2019, Editorial Department, Journal of South China University of Technology.
