电动舵系统驱动组件优化设计

Optimum design of drive assembly in electromechanical actuation system

电动舵系统以其独特优点广泛应用于导弹制导控制系统，随着导弹武器系统战术指标的提高．必须对电动舵系统的核心单元——驱动组件进行优化设计。由于负载高动态以及参数耦合，常规设计方法需要烦琐、反复的计算和仿真。论文分析了舵面的运动和负载特性，并进行等效处理，通过参数解耦，采用分步设计方法，以图解形式实现了电动舵系统驱动组件的可行性检验和最优化设计。提出的设计方法简便、直观、高效。

Due to its unique virtues, electromechanieal actuation system （EMAS） is widely adopted in missile＇s guidance ＆ control systems. With the increasing higher requirements to missile weapon system, it is imperative to optimize the design of EMA＇s core component, Drive Assembly. EMA＇s load has high dynamic characteristics as well as complex parameter coupling, therefore conventional EMA＇s design needs complex and iterative calculations and simulations. Motion and load of control surface is equivalently analyzed. Benefit from parameter decoupling and multistep design, the feasibility check and optimization of EMA＇s drive assembly design are realized with graphical representations. The proposed design method has distinguishing features： simple but convenient and efficient.
