Controller: The controller is the core of the machine. The standard is defined as: changing the wiring of the main circuit or control circuit in a predetermined order and changing the resistance value in the circuit to control the starting, speed, braking and reverse of the motor. It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is the "decision-making body" that issues commands, that is, completes the coordination and direct operation of the entire computer system. Electricity is the first-level discipline of its application, and power distribution and electricity use are secondary disciplines.
