Title:
DIGITAL CONTROLLER
Document Type and Number:
Japanese Patent JPS61114304
Kind Code:
A
Abstract:
PURPOSE:To shorten the sampling time and to attain the servo control at a high speed by using exclusively a digital signal processor to perform each operation of servo control. CONSTITUTION:A target position Xc, a target speed Vc, etc. are delivered from a host processor 1, and a motor 13 is controlled via a D/A converter 11 and a power amplifier 12. Here a digital signal rocessor DSP10 is provided and executes exclusively the multiplication and addition at a high speed for voice synthesization, etc. The DSP10 contains an observer 10-1, an integration circuit 10-2, a function generating circuit 10-3, an arithmetic circuit 10-4, etc. Thus the DSP10 reads the present position by an encoder 14 for each sampling time point and at the same time calculates the optimum control amount U. The motor 13 is controlled by the control amount U.
