摘要
本文以某飞行器纵向运动回路作为对象研究了非线性系统的变结构控制问题,给出了该飞行器变结构控制的切换函数和控制规律,并通过仿真验证了该方法的有效性。结果表明,飞行器适应性较强,该设计方法对高性能飞行控制系统的设计有很大实用价值。
In this paper, the transformation from nonlinear systems to controllability canonical form is studied, and a contruction theorem is given. On the basis of this investigation, a variable structure control of flight altitude moving loop is discussed, and switching function and control law of the variable structure control is given. The simulation results show that the design is satisfactory, has a wide adaptability to the fligh control systems, and it is very useful in the design of high quality systems.
