Title:
CONTROLLER
Document Type and Number:
Japanese Patent JPS59140516
Kind Code:
A
Abstract:
PURPOSE:To improve the speed of response of a controller, by using an arithmetic device having a special function in a control system and attaining an output coinciding with a target value at the second sampling. CONSTITUTION:A control object 1 is divided to a static characteristic part 10 and a dynamic characteristic part 20, and a nonlinear response is performed in the static characteristic part 10, and an input signal ei and a control signal ec are inputted to output a virtual variable e'0 to the dynamic characteristic part 20 of the next stage. The operation of an equation I is performed in the static characteristic part 10, and the operation of an equation II is performed in the dynamic characteristic part 20, and an output signal e0 is outputted. This output e0 is detected by a detector 2, and the detected signal is supplied to an arithmetic device 3 of the next stage. The output signal and a target value eR are inputted to the operator 3 at a prescribed sampling period SP to output the new control signal ec from a holding element 4. The output signal e0 coinciding with the target value eR is outputted as the second sampling to improve the speed of response of the controller.
