中文摘要：

雷达天线的性能主要取决于其伺服系统的设计水平。伺服系统的设计包括结构设计和控制设计两部分,这两部分是相互影响紧密耦合的。一般所采用的设计方法是对结构系统和控制系统先分别设计,然后再根据要求进行调校,这往往会导致产品研制的周期长、成本高、性能差、结构笨重,不能保证伺服系统总体的综合性能最优。针对雷达天线伺服系统设计中存在的结构设计与控制设计相分离的问题,提出一种结构与控制集成优化设计的模型,给出求解策略与方法,并进而应用于三个典型例子,取得了满意的结果。数值例子和实物试验都验证了上述雷达天线伺服系统结构与控制的集成设计模型与方法的有效性和正确性。该模型与方法对其他伺服系统的设计也具有一定的参考和借鉴价值。

英文摘要：

The performance of radar antenna mainly depends on the design level of its servo system.The design consists of two parts,structural design and control design.These two parts are interacting and closely coupled.Usually,the structure and the control are designed respectively,and then they are adjusted according to the requirement.This method often leads to long product development cycle,high cost,poor performance,and bulky structure,thus being unable to ensure the optimal comprehensive performance of the whole servo system.A design model of integrated structure and control is proposed to give the solving strategy and methodology,and they are applied to three typical examples,and satisfactory results are obtained.Both numerical examples and practical experiments demonstrate the validity and correctness of the new model and method,and they are also valuable to the design of other servo systems.
