Abstract:To improve the dynamic characteristics of two-dimensional heavy-duty precision turntable, the control characteristics of the system are simulated and analyzed based on multi-software mechatronics joint simulation with AMEsim, ADAMS and Simulink. In this paper, the joint simulation model includes the motor model, the dynamic model of two-dimensional heavy-duty precision turntable and the PID control model which are established by AMESim, Adams and Simulink tools respectively, this joint simulation model is then used to simulate and analyze the step response of the system. Aiming at the problems of time-varying nonlinear load interference and other factors in the system, adaptive fuzzy PID control algorithm is used to optimize the control of the system. The simulation results show that the fuzzy PID control algorithm has the advantages of fast response and no overshoot, and the stability error is reduced by about 37% compared with the common PID control.
