Fast optimization estimation algorithm of high precision MSCMG angular measurement

In order to improve Magnetic Suspended Control Moment Gyro (MSCMG) gimbal system rate servo precision, and overcome the shortcomings of the limited angular measurement accuracy of resolver, this paper presents a fast optimization estimation algorithm of high precision MSCMG angular measurement. 'The angular position and speed is estimated at real time according to the position signal from resolver transducer, so the random noise is restrained. Through improved filtering gain determine way, (he computational complexity is reduced. Finally this method was conveniently implemented on DSP and the experiments show that the method is effective and practical to improve angular measurement accuracy, then high precision rate servo performance is acquired using low precision sensor.
