Proportion Integration Differentiation (PID) Control Strategy of Belt Sander Based on Fuzzy Algorithm.

Aiming at solving the problems of response lag and lack of precision and stability in constant grinding force control of industrial robot belts, a constant force control strategy combining fuzzy control and proportion integration differentiation (PID) was proposed by analyzing the signal transmission process and the dynamic characteristics of the grinding mechanism. The simulation results showed that compared with the classical PID control strategy, the system adjustment time was shortened by 98. 7%, the overshoot was reduced by 5. 1%, and the control error was 0. 2%- 0. 5% when the system was stabilized. The optimized fuzzy control system had fast adjustment speeds, precise force control and stability. The experimental analysis of the surface morphology of the machined blade was carried out by the industrial robot abrasive grinding mechanism, and the correctness of the theoretical analysis and the effectiveness of the control strategy were verified.
