Define controller, plant, actuator
Short answer
Controller: hardware/software computing control signal from error between set-point and measured output (e.g., microcontroller with PID). Plant: physical process (motor, oven) whose output is regulated. Actuator: converts controller signal into physical action (motor, valve, heater).
Define the following terms used in control system: Controller, Plant, Actuator.
- Controller: the part of the system (hardware or software, e.g. a microcontroller running a PID algorithm) that takes the error between the set-point and the measured output and computes the control signal.
- Plant: the physical process or system being controlled, such as the car, a motor, an oven or a tank, whose output (speed, temperature, level) is to be regulated.
- Actuator: the device that converts the controller's signal into a physical action on the plant, such as a motor, valve, heater or throttle servo.
