| Abstract: |
| According to the shortage of H ∞ controllers in time-domain performance, mixed H 2/H ∞ control problem was investigated For a species of systems with structured perturbations, the sufficient and necessary condition that there were mixed H 2/H ∞ controllers and the method to design a controller were presented The simulation results for a certain double spool turbojet aero-engine reveals that the robust control with no static error for both rotational velocity of low-pressure rotor and temperature at low-pressure turbine outlet in the same time can be realized And the dynamic performance character of closed loop system is also improved evidently |
