| Abstract: | The paraffin oil level control system in capsule forming machine is a nonlinear, time-variant and coupling system. The mathematical model of the level control system was established. And a new model reference fuzzy adaptive PID （MRFA-PID） control method was proposed by combining the adaptive control, fuzzy control and PID control techniques. Without need to identify the parameters of the controlled plant, the proposed method has a good real-time performance, and is easy to be implemented on line. Simulation results show that the proposed method is efficient to design a robust paraffin oil level control system for capsule forming machine with good dynamic character and high regulation precision. Even though the parameters＇ perturbation reaches 20%, the closed-loop system still has satisfied dynamic performance.The effectiveness of the proposed method is also verified by physical experiment. |
