一、问题的提法一般在设计系统时,是在执行机构(或/和对象)一定的情况下,满足典型信号作用之下的动静态性能指标。过渡过程时间最短问题在理论上一般采用极值原理或线性二次准则等方法来处理。而实际上如果采用状态反馈法结合“模型”控制器也可达到非常理想的效果。 First, the problem formulation Generally in the design of the system, the actuator (or / and object) under certain circumstances, to meet the typical signal under the action of static and dynamic performance indicators. The problem of the shortest transition time is theoretically dealt with by extreme value principle or linear quadratic method. In fact, if the state feedback method combined with the “model” controller can achieve very good results.
