Title:
SIGNAL PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/159116
Kind Code:
A1
Abstract:
Provided is a signal processing system (1) that reduces possible noise in a subject to be controlled (2) by superimposing a compensation signal on a control signal for controlling operation of the subject to be controlled. The signal processing system is provided with a signal generation unit (17) generating the compensation signal in accordance with a prescribed algorithm, a state sensing unit (16) sensing the state of the algorithm and sensing at least a divergence state thereof, and a phase shift unit (14) shifting a phase of the compensation signal through a prescribed angle when the state sensing unit senses the divergence state.
