SYSTEM AND METHOD FOR ESTIMATING SPEED IN STABILIZING SYSTEM USING GYROSCOPE

摘要

PURPOSE: A system and a method for estimating speed in a stabilizing system using a gyroscope are provided to reduce the volume and costs of the stabilizing system by adding a simple circuit for estimating speed without a speed meter. CONSTITUTION: A first adder(10) adds a control signal to be controlled through the stabilizing system and an output of the gyroscope(40) to a feedback value of an anti-windup controller. A first function part(51) multiplies the output of the first adder by Km/H to output the calculated value. A second adder adds an output having a negative sign to be controlled to the output of the first function part. The gyroscope(40) compensates a motion value using the output of the second adder. A feedback has a dead zone(52) for the output of the gyroscope and is to be fedback in accordance with predetermined gains. A speed estimator multiplies the output of the gyroscope by the gain of the feedback to use the calculated value as a speed estimated value.
