Putting forward with an integrated flight and aeroelasticity control method of elastic air vehicle and aiming at the reduction errors introduced during combination dynamic model reduction, the paper adopts mixed sensitivity H∞control to design low-order combination control law that satisfies its robustness based on reduced-order model. Against to the wide reduced-order error bounds that may influence control performance, the two-circuit design method is used, and combined with inner-circuit suboptimal feedback design, error bounds of equivalent model are greatly narrowed. Without any orders extra added to the controllers, the outer-circuit robust controller designed on that basis will effectively improve the performance of the system, significantly superior to the single circuit design method. It is shown in simulation results that such low-order combination law will not only provide satisfactory robustness and performance, but will also effectively suppress the occurrence of servo flutter, while the greatly-reduced orders will be helpful for the realization of projects.

In this paper, an adjustable constant current circuit is designed by combining the digital potentiometer X9312 and the microcontroller 89C52. We first introduce the overall component and structure of the constant current dimming circuit which needs to be designed. Then, the hardware circuit design and the software design are discussed in detail. Based on the proposed design method, the manufacturing and the testing of the prototype machine are taken at last. The testing results are satisfactory, and meet the design requirement. The proposed design approach has won award in 2009 National Undergraduate Electronic Design Contest.
