Title:
SERVO MOTOR CONTROL SIGNAL GENERATION SYSTEM FOR PROPORTIONAL TYPE RADIO CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3819466
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To secure the fast responsiveness and also to optionally vary the frame time within a limited frequency band by converting the frequency of the frame time signal of an input pulse string having its modulated width into an optional frame time signal.
SOLUTION: A pulse width/voltage conversion circuit 1 inputs the pulse string which is repeated by the frame time signal of the prescribed frequency that undergone the modulation of width for control of a servo motor and converts the pulse string into the voltage signal corresponding to the pulse width. A frame time signal oscillation circuit 2 oscillates the individual frame time signals of different repetitive frequency independently of the frame time signal of the prescribed frequency. Then a pulse width modulation circuit 3 performs the pulse width modulation of the voltage signal converted by the circuit 1 by means of the frame time signal outputted from the circuit 2. Thus it is possible to easily and optionally vary the frame time of the control signal and also to correspond to a servo system having the fast responsiveness.
