摘要：

In view of that the diaphragm spring for clutch has a nonlinear stiffness with a negative value in some travels, so may lead to system instability and the low control accuracy in clutch position, a nonlinear control scheme combining differential flatness feedforward and gain self-turning feedback is proposed. The results of simulation and experiment verify the instability phenomenon caused by the negative stiffness of diaphragm spring. Compared with the traditional control method without considering the negative stiffness characteristics of diaphragm spring, the nonlinear control scheme proposed can eliminate instability phenomenon with small tracking error. © 2020, Society of Automotive Engineers of China.
