　　控制器

　　控制器是指按照预定顺序改变主电路或控制电路的接线和 改变电路中电阻值来控制电动机的启动、调速、制动与反向的主令装置。控制器由程序状态寄存器PSR，系统状态寄存器SSR， 程序计数器PC，指令寄存器等组成，其作为“决策机构”，主要任务就是发布命令，发挥着整个计算机系统操作的协调与指挥作用。 控制的分类主要包括两种，分别为组合逻辑控制器、微程序控制器，两个部分都有各自的优点与不足。其中组合逻辑控制器结构相对较复杂，但优点是速度较快；微程序控制器设计的结构简单，但在修改一条机器指令功能中，需对微程序的全部重编。

　　controller

　　The controller refers to the master device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to the predetermined sequence. The controller is composed of program status register PSR, system status register SSR, program counter PC, instruction register, etc. as a "decision-making body", its main task is to issue commands and play a coordinating and commanding role in the operation of the whole computer system. The classification of control mainly includes two kinds, namely, combinational logic controller and microprogrammed controller. Both parts have their own advantages and disadvantages. The structure of combinational logic controller is relatively complex, but its advantage is that its speed is faster; The structure of the microprogramming controller is simple, but in modifying a machine instruction function, it is necessary to reprogram all the microprograms.
