一种可重构飞行控制系统设计的新方法

On Improving Pole-Displacement Method for Designing Reconfigurable Flight Control System

介绍利用滑模越近律进行极点配置设计控制器的新方法。在此基础上，利用该极点配置方法进行可重构控制器的设计。由于该方法采用降维设计并由所需极点进行滑模参数的选择，设计过程具有规范性。从而在实际应用中将大大减少计算量，对实时控制具有实用价值。

Real - time caiculations that need be performed by recondgurable flight control system demand that time required for such calculations be as short as possible. We found that making judicious use of sliding - mode and its tendency -rate can be helpful. We propose an improved pole - displacement method based on sliding - mode (eq. 6) and its tendency - rate (eq. 8). All pole - displacements can be computed with eqs. (7) and (8) respectively. Then the control law is given by eq. (9). Thus the desisn is systematic and normalized and its order is reduced, making short real - time calculations possible. We took a numericai example and performed simulation calculations for various cases. Results for longitudinal control are presented in Figs. 1 and 2 and results for lateral control are presented in Figs. 3 and 4. These results indicate that our proposed Anprovement works quite well.
