采用基于张量积的T-S模糊建模与控制方法,对微型飞行器过失速降落纵向运动的轨迹跟踪控制问题进行了研究。首先,建立了过失速降落中飞行器纵向运动的线性变参数动力学模型;然后,通过张量积模型转化方法,将线性变参数模型转化为张量积胞体模型,基于该模型设计了并行分布补偿控制器,用Lyapunov稳定性理论证明了闭环系统的稳定性,并推导了区域极点配置条件以获得更好的暂态响应性能;最后,对飞行器的过失速降落过程进行了仿真,验证了所设计的跟踪控制器的有效性。
The T-S fuzzy modeling and control method based on tensor product is used to study the trajectory tracking control of the longitudinal movement of stalls during stalling. First of all, a linear variable parameter dynamic model of the vertical movement of the aircraft during landing over a stalling speed was established. Then, a linear variable parameter model was transformed into a tensor cumulus model through the tensor product model transformation. Based on the model, parallel distributed compensation Controller, the stability of the closed-loop system is proved by the Lyapunov stability theory, and the regional pole placement conditions are derived to obtain better transient response performance. Finally, the process of the stall landing of the aircraft is simulated, The effectiveness of the tracking controller.
