摘要

This work studies an H2/H∞ control method for mobile satcom antenna (MSCA) servo systems. To achieve the otpimal tracking performance, an H2 optimal feedback controller is designed by using linear quadratic (LQ) optimal method. And then an H∞ suboptimal feedforward controller is designed for disturbance rejection. Considering the effects of main resonance modes, a design example is given to illustrate the parameters tuning process. Finally, the effectiveness and advantages of this design approach are verified by simulation and experiment results.
