Title:
PI CONTROLLER
Document Type and Number:
Japanese Patent JPS5922102
Kind Code:
A
Abstract:
PURPOSE:To improve the precision of a PI controller which varies a proportional gain and an integral time automatically and to facilitate its handling by converting parameters of adaptability into parameters relating to values on a time axis. CONSTITUTION:A PI control constant adjusting part 11 inputs the proportional gain K of a controlled system and calculates the proprotional gain KP and integral time T1 of PI control. Quickness parameters alpha and T are so set that the time when control response reaches 100.alpha(%) as a final value in response to stepwise variation in the command of the controlled system is T. Further, a stability parameter beta is so set that while beta>1.0, beta=1/omegaCTI. Therefore, the parameter beta as an index of stability is settable in addition to the parameters alpha and T as indexes of quickness, so the arithmetic expression of the proportional gain KP and integral time TI is derived from the results of the simulation of many controlled systems.
