跟踪系统的计算机辅助设计,是借助于系数平面模型、环路波德图以及使二乘方指数最小等途径实现的。采用经典性能指标,并通过将注意力集中在系数平面的常用区域,而把设计方法直接与现有的令人满意的工程设计直接联系起来了。在详细介绍的例子中包括这样一个实例,它表明:当系统改变时,通过硬件反馈可使性能的变化减小。而以采用观察器的状态变量估值为基础的相应设计,则不能得到类似的简化。为得到一个与性能技术指标相适应的低阶补偿器,引入了一种最小均方差算法。
Computer aided design of tracking system is achieved by means of coefficient plane model, loop Bode plot and the least squares method. Using classical performance indicators, and by focusing on the common area of the coefficient plane, the design approach is directly linked to the existing satisfactory engineering design. An example is included in the detailed example, which shows that performance changes can be reduced by hardware feedback as the system changes. Similar design based on state variables estimation using observers can not be similarly simplified. In order to obtain a low-order compensator that is compatible with the performance specifications, a minimum mean square error algorithm is introduced.
