The controller refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit according to the predetermined order to control the starting, speed regulation, braking and reverse direction 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, to coordinate and direct the operation of the entire computer system.

The controller is divided into a combinational logic controller and a micro-program controller, both of which have their own advantages and disadvantages. The combinational logic controller is troublesome to design and has a complex structure. Once the design is completed, it cannot be modified or expanded, but it is fast. The microprogram controller is convenient in design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, it only needs to reprogram the corresponding microprogram; However, it does so by executing a shred. The specific comparison is as follows: Combinatorial logic controllers, also known as hard-wired controllers, are composed of logic circuits and rely entirely on hardware to realize the functions of instructions.
