The desired state. This value is used as the reference point for a controller’s error calculation.
Measurements from sensors.
- process variable
The term used to describe the output of a plant in the context of PID control.
The term used to describe the reference of a PID controller.
A term encompassing a plant and it’s interaction with a controller and observer, which is treated as a single entity. Mathematically speaking, a system maps inputs to outputs through a linear combination of states.
The system or collection of actuators being controlled.
- control input
The input of a plant used for the purpose of controlling it
- control effort
A term describing how much force, pressure, etc. an actuator is exerting.
- steady-state error
- step response
- step input
- rise time
- settling time
- system response
A set of mathematical equations that reflects some aspect of a physical system’s behavior.
