【摘要】 在电传飞机纵向自动驾驶仪控制律的初步设计过程中，以电传飞机的纵向低阶等效系统为控制对象，采用零极点偶配置方法合理地配置零极点偶，使纵向自动驾驶仪控制律的设计得到了最大程度的简化。用所获得的控制律进行了数字仿真，仿真结果表明，纵向自动驾驶仪各个功能模式获得了良好的动态响应特性，满足了各项指标的要求，从而证明了这种设计方法是简便可行的。更多还原

【Abstract】 In the course of preliminary control law design of longitudinal fly-bywire autopilot, with longitudinal low-order equivalent model taken as the control object, the design obtained simplification to the great extent by means of matching the zero and pole pairs reasonablly. The digital simulation is accomplished with the obtained control law, and the simulation results show that all of the autopilot function modes possess good transient response and meet requirements, then prove that the design is simple and feasible.更多还原
