膜片弹簧的非线性弹性特性给汽车离合器的高精度自动控制带来 困难。针对这类特性已知的 非线性输入，根据广义能量原理和反函数定理设计非线性补偿器，从理论上证明了闭环控制 回路的渐进稳定性。该补偿器应用于膜片弹簧离合器的自动控制，跟踪期望输出轴角速度。 仿真表明，非线性控制器是渐进稳定的，跟踪品质明显优于线性控制器。
The non-linear spring characteristic of the diaphragm spring brings difficulty to the high-precision automatic control of the automobile clutch. According to the known nonlinear input of such characteristics, the nonlinear compensator is designed according to the generalized energy principle and the inverse function theorem, and the asymptotic stability of closed-loop control loop is theoretically proved. The compensator is used in the automatic control of the diaphragm spring clutch to track the desired output shaft angular velocity. The simulation shows that the nonlinear controller is asymptotically stable and the tracking quality is obviously better than the linear controller.
