| Abstract: | The paper proposes a design strategy based on state feedback and feedforward compensator for an inner loop of helicopter flight control system.This strategy is used to achieve the four independent channels tracking the given model.The desired model depends on the handling qualities specifications;the inner loop decouples the dynamics and handlings,and makes the system have desired command response characteristics,the design of outer loop can be simplified consequently.Time-history simulations illustrate the strategy can attain excellent control performance. |
