自动控制更广泛的含义不仅是控制机器自动完成一个給定的过程,而且是控制机器在一定意义下“最佳地”完成这一过程。例如:控制火箭射中一个目标,但消耗的燃料最小;控制容量一定的电机完成一个給定的行程,但所需的时間最短等等。实际上,对于任何系統的自动控制都存在着一定意义下最佳化的要求;但是,这种要求的具体实現需要依靠电子計算技术或者复杂的控制机构,因此,对于一般自动控制系統就不去考虑这个問題。現代工程系的发展,其重要特征是精确度的要求提高、限制条件增加以及需要更多地考虑經济性;在这样情况下,实現一定意义下最佳化的控制就显得完全必要,否則,不能滿足系統运行的要求,或者是极不經济的,与此同时,現代电子計算技术的发展
The broader meaning of automatic control is not only to control the machine to automatically complete a given process, but also to control the machine to “perfectly” complete this process in a certain sense. For example: control the rocket to shoot a target, but the fuel consumed is minimal; the motor with a certain control capacity completes a given stroke, but the required time is the shortest. In fact, there is a certain degree of optimization required for automatic control of any system; however, the specific implementation of this requirement requires the use of electronic computing technology or a complex control mechanism. Therefore, it is not necessary for general automatic control systems. To consider this issue. The development of the modern engineering department is characterized by an increase in precision requirements, an increase in restrictions, and a need to consider more economically; under such circumstances, it is absolutely necessary to achieve optimal control in a certain sense. Otherwise, Can not meet the requirements of system operation, or is extremely uneconomical, at the same time, the development of modern electronic computing technology
