【 摘 要 】

A general test turntable was designed and developed for the test of the bomb chamber, and in-depth research on the system oscillations and long system response time that occur during the test of different load processes are given. A fuzzy adaptivePID control method is proposed. Taking the errore and the error change rate ec as inputs, the fuzzy parameters are used to modify the PID parameters online to meet the requirements of e and ec for PID parameter self-tuning under different loads, which will eliminate the oscillations and increase the response speed of the system. Through system modeling and simulation, the control effects of common PID control and fuzzy adaptive PID control under different loads are compared. According to the simulation analysis, the fuzzy adaptive PID control can recognize the change of the load in time compared with the normal PID control, which will help to adjust the PID parameter of the system accordingly, so that the system maintains a certain response speed.
