Study on the intelligent hybrid control for secondary regulation transmission system

Influenced by the factors such as deadzone, hysteresis loop, coulomb friction and working conditions during working, the hydrostatic transmission system with secondary regulation is nonlinear typically. So speaking strictly, there is no a control method which is suitable for the whole process of the controlled object, it is difficult to obtain famous control effect by use of conventional control method, and it is necessary to develop the most suitable control method according to different controlled-object. In order to overcome the nonlinearization of the secondary regulation system, the neural fuzzy control is embedded in the expert control, a compositive real-time intelligent hybrid control method is produced. Not only has the controller ability of logical reasoning and advanced intelligent behavior of the expert control, but the instinct reasoning ability of the neural fuzzy, the coupled control method realizes the parallel control and knowledge sharing. The system control performance is satisfied, the designed controller presents a good rapidity and flexibility, and the system moves smoothly.
