摘　　要：将成熟的极点配置算法引入带状态反馈约束的自动驾驶仪设计中,提出了利用极点配置的求解工具将带状态反馈约束系统的非线性方程求解问题的阶数降低这一设计思路。具体方法是设置极点约束,利用极点配置求解的方便性,将极点配置算法求得的反馈增益与状态反馈约束组成非线性方程组,使原来的n阶非线性方程求解问题降阶,从而降低求解难度,通过求解非线性方程组进而完成自动驾驶仪设计。随后通过具体的带状态反馈约束的滚转驾驶仪设计例子验证了这一设计思路是可行的。With the help of the pole placement method, the order of the nonlinear equations for the state-feedback constrained autopilot decreased. Making use of the facility in solving the pole placement problem, the feedback gain metrics was obtained easily by settling the poles’ position. The state feedback constraints together with the state feedback gains compose the nonlinear equations. So the order of the nonlinear equations, formerly is n, now decreases to the number of the constraints. Solving the nonlinear equations, the design of the state feedback constrained autopilot can be finished. Subsequently, a roll control autopilot example was introduced to prove the correctness of the method.
