由于高速电子计算机和控制理论的迅速发展,用电子计算机控制生产过程已得到广泛应用,从而使生产水乎大大提高。根据现代控制理论,用电子计算机控制生产过程,首先要用数学方法较精密地描述生产过程,建立描述生产过程动态特性的数学模型,并化为状态空间表达式,这就是“系统辨识”;在此基础上,进一步寻找生产过程的最优控制规律,使系统在变化过程中能按某种最理想的方式运动,这就是“最优控制”;在给出了最优控制公式与有关参数后,在实时控制时,还必须设计一套状态滤波公式,以便根据输入输出信息,用滤波公式来确定每一
Due to the rapid development of high-speed electronic computers and control theory, the computerized production process has been widely used to greatly increase the production of water. According to the theory of modern control, to control the production process by the electronic computer, we must describe the production process more accurately by mathematical methods, establish the mathematical model that describes the dynamic characteristics of the production process, and transform it into the state space expression. This is the “system identification” On the basis of this, further searching for the optimal control law of the production process enables the system to move in some optimal way in the process of change, which is called “optimal control”; after giving the optimal control formula and the related parameters , In real-time control, you must also design a set of state filter formula, in order to input and output information, using the filter formula to determine each
