单片机广泛应用于自动控制系统中,用于对过程(如化学过程、热力学过程、机械加工过程等)和对象(如设备等)进行控制。单片机作为控制器,它的任务在于按照某一变量(即过程变量)的测定值调整过程的状态,使之稳定在标准值上。控制器的操作方式称为控制法则或控制-The microcontroller is widely used in automatic control systems for process control (such as chemical processes, thermodynamic processes, machining processes) and objects (such as equipment, etc.). SCM as the controller, it is the state of the process of determination of value adjustments in accordance with a variable (ie process variables), so that stability in the standard value. The controller mode of operation referred to as control algorithms or control
