For the issue that applying traditional method of quantization factor fuzzy control for magnetic powder clutch in the engaging process during vehicle starts can not achieve optimization, a method of using variable learning factor partial swarm to optimize quantization factor of fuzzy controller has been put forward, the optimized quantization factor changes with the environmental condition as well...
As for clutch control during automatic mechanical transmission (AMT) starting, it is difficult to design an effective and adaptive control strategy. Aiming at it, an improved constant engine speed control strategy is adopted as a total control principle, and on basis of it a new fuzzy control strategy using throttle opening, relative deviation between engine speed and its target and engine speed change...
While automotive start, there are some problems during clutch jointing control, such as nonlinearity and time-variant. According to partial constant revolution control principle of the engine while vehicle starts, a double closed-loop control system is designed for vehicles with AMT, which is made up of fuzzy turning PID controller and single nerve cell adaptive PID controller. Some experiments are...
For automatic clutch control system, precise and quick position tracking is difficult on account of its nonlinear character. A new clutch actuating mechanism with a whirl spring was devised for torque compensation to reduce the load of DC actuator and improve the dynamic performance of clutch control system firstly, and then a neuron adaptive PID controller with feedforward and adjustable gain was...
