Title:
GIMBAL CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH07312518
Kind Code:
A
Abstract:
PURPOSE: To improve the directivity of a spaceship antenna by correcting the flexibility of an inertial gimbal by a differentiation processing in an inside feedback loop connected with the gimbal, and simultaneously connecting an outside feedback loop having an automatic tracing receiver. CONSTITUTION: In an inside control loop 21 for deciding the position of an antenna 11, the relative angle of a gimbal 13 is measured by a resolver 14, and a signal processed by a differentiation type resolver processing circuit 22 for correcting the flexibility of the gimbal 13 is added to an outside signal, and added through a motor driving circuit 26 to a gimbal driving device 27. An angle position related with the absolute reference of the antenna 11 is controlled by an outside control loop 23. An error signal from an automatic tracing receiver 19 is transmitted through a filter 33, A/D converted by a converter 34, P-I compensated by a compensating circuit 35, transmitted through each control mode switching circuit, and added to an inside control loop signal by an adder 24.
