US 7,340,336 B2 · Plant control system

Abstract

A plant control system using response specifying control that makes it possible to independently set a follow-up behavior for an output value of a plant when a target output value of the plant changes and a convergent behavior for a difference between a target output value and an output value when the output value of the plant changes. The control system has a controller for determining a clutch stroke on the basis of a model equation of a clutch device such that a target rotational speed and an actual rotational speed of the clutch device coincide with each other. The controller includes a target value filter for carrying out filtering computation on a target rotational speed to calculate a filtering target value that converges to the target rotational speed with a response delay, and a response specifying control unit that determines the clutch stroke by response specifying control such that the filtering target value and the clutch rotational speed coincide with each other.

A plant control system for determining a control input value for a plant such that an output value of the plant coincides with a target output value, comprising:

filtering means for carrying out a predetermined filtering computation on the target output value to calculate a filtering target value that converges to the target output value with a response delay;
and
control input determining means that uses response specifying control that allows a convergent behavior for a difference between the filtering target value and the output value of the plant to be variably specified so as to calculate a reaching law input based on a switching function value that defines the convergent behavior for the difference, thereby determining a control input to the plant on the basis of the reaching law input.
