Description
Summary:As the control system of the ship's crane is nonlinear, time-varying and large inertia, the traditional way to control is difficult to achieve control requirements. The text have the deck crane' electro-hydraulic proportional valve as the research object, use the way of optimizing input's fuzzy domain which called variable domain fuzzy PID, to solve the weakness of traditional control and bring out the Marine crane hoisting speed lord's optimization control. The experimental results show that, compared with the conventional PID and fuzzy PID, variable domain fuzzy PID has advantages of good real-time performance, fast response, strong anti-interference characteristics and good dynamic characteristics. The new way also has good control effect, can better able to meet the system control requirements.
