Control of electromagnetic clutch during vehicles start

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 carried out, and the results proved that, there are two obvious benefits of the double closed-loop control system is applied. One is that clutch jointing control is easier, the other is that automotive start more steadily and the sliding friction work is decreasing.
