| Abstract: | An electric actuator has only one invariable adjusting speed ,which is difficult to carry out its accurate orientation and soft shut. This paper makes a study of a two-closed-loop control mode, that is to make both position and speed closed loops adjustable by taking the valve position increment as an independent variable to establish both position loop model with a given speed and speed loop model with fuzzy parameter self-tuning PID. Simulation shows that this mathod makes it possible for the electric actuator to carry out its accurate and quick orientation and soft shut. |
