Modern Control Theory Used in the Design of Servosystem for Large Precision Radar

In the servosystem for large precision radar,some problems that are relatedto the oscillation of velocity difference,the harmonic oscillation in the transmitting mechanism,and the load disturbance compensation have been analyzed with the aidof modern control concepts,such as state feedback,disturbance compensation,andstate observer etc.And a new method is proposed that facilitates the radar servo-system design.
