| Abstract: |
| In order to solve the multi-variable control problem for variable geometry ramjet engine, the H∞ mixed-sensitivity robust multi-variable controller is designed. On the basis of large deviation nonlinear dynamic model, the simulation is scheduled to compare the performance for single-variable multi-loop controller. Simulation and experimental results show that this method has smaller pressure overshoot and larger stability margin. |
