| 摘 要： | 基于线性变参数系统的变增益控制克服了传统变增益的缺点,其关键所在就是系统非线性模型向线性变参数模型的转化;讨论了目前广泛应用的三种线性变参数建模方法,并分析了它们各自的缺点,同时,在此基础上对其中的一种方法进行改进,最后利用该方法对一类无尾式飞行器进行了线性变参数建模;仿真结果及其性能评估结论表明,改进方法较之原方法在性能评测上效果提高了十倍,同时仿真结果也显示误差在允许范围之内,得到了满意的结果.

| Abstract: | The disadvantages of traditional gain-scheduling are overcome based on linear parameter varying(LPV) model.Translating the nonlinear model into LPV model was the key to apply gain-scheduling based on LPV.Three methods of translating nonlinear model into LPV were discussed,and their disadvantages were analyzed respectively.An improved method based on one of three methods was proposed.The proposed method was applied to the tailless aircraft.The simulation result shows the performance is improved about ten tim... |
