ABSTRACT:
A clutch slip control device includes: a slip revolution speed detecting circuit for detecting an actual slip revolution speed of a clutch; a memory unit for storing constants set to satisfy response and stability of a feedback control system of the slip conditions, the constants being determined by a high-order function approximating variation in input-output frequency characteristics of a plant input for actuating the clutch and the actual slip revolution speed; a first calculation circuit for calculating a first parameter using the constants stored in the memory unit, the first parameter discretely reflecting past data of the plant input, which are obtained in a current feedback control cycle through in a cycle executed a plurality of times before; a second calculation circuit for calculating a second parameter using the constants stored in the memory unit, the second parameter discretely reflecting past data of a deviation of the actual slip revolution speed from a target slip revolution speed, which are obtained in the current feedback control cycle through in the cycle executed a plurality of times before; and a plant input determination circuit for determining a next plant input based on the first parameter and the second parameter.
