Abstract
In order to solve the resonance problem of the position servo system under a flexible load, this paper proposes an improved mathematical model of the notch filter, and uses bilinear transformation to complete the design of the digital filter. After simulation analysis, the frequency characteristics of the filter are consistent with the theoretical design, and the parameter adjustment is precise and controllable. An experimental verification was carried out on the flexible nozzle load of the solid rocket. The experimental results show that: adding an improved notch filter to the control loop of the position servo system can effectively suppress the position resonance problem.
