Title:
CONTROLLER
Document Type and Number:
Japanese Patent JP3164667
Kind Code:
B2
Abstract:
PURPOSE: To improve a response characteristic much more than conventional PID with one degree of freedom and PID with two degrees of freedom so as to make a grade much higher.
CONSTITUTION: In a controller which executes at least a PI control operation in such a way that a deviation between a target value and a controlled variable obtained from a controlled system 1 through a feedback line is set to be zero and impresses operation output obtained by the control operation on the controlled system, a controlled variable filter 10 becoming an advance/delay element where time proportional to reset time for the PI control operation is set to be advance/delay time is inserted into the feedback line.
