Title:
NONLINEAR CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JPS61278903
Kind Code:
A
Abstract:
PURPOSE:To constitute arbitrarily a control system having the response, matching specification and deviation suppression characteristics, which a designer intends, by generating an arbitrary drive force in a nonlinear type with respect to the combinations of a following error signal, its differential and integral values. CONSTITUTION:The following error signals from a discriminater 2 are passed through a differentiation circuit 3 and an integration circuit 5 as they are converted into digital signals by A/D converters 5-7, and inputted as the address signal of a drive force data generating ROM 8. then drive force data deciding the drive force which a DC brushless motor 11 has to generate is outputted as an output with respect to the combination of said values to a D/A converter 9, Its output is inputted to a constant current drive circuit 10, drives the DC brushless motor 11 and a control system 12.
