Title:
DISCRETE TIME CONTROLLER
Document Type and Number:
Japanese Patent JPS6394304
Kind Code:
A
Abstract:
PURPOSE:To improve a responsiveness at the time of a rise and to execute a stable control at the time of a steady state by using an adaptive on and off control function in a transient state and executing a minimum discrete control in the steady state. CONSTITUTION:In the transient state, the controlled variable is detected for a prescribed sampling time, an operation by a binary switching is carried out to a controlled system for every sampling interval, the parameter of the model of the controlled system is estimated based on the controlled variable and the manipulated variable by using the discrete time type adaptive on and off control means 5 and the controlled variable sequence predicted as a response when the manipulated variable throughout several steps in future is applied to the model is estimated. In the steady state, the minimum discrete control 32 is carried out from the parameter of the model of the controlled system obtained at the time of controlling the transient state is executed and the controlled system is controlled by the successive control for the controlled variable according to a self-tuning.
