| Actuator |
The part of a control system that converts the controller's output into a physical action or signal. |
| Brushless DC Motor |
A motor that uses electronic commutation instead of brushes to control the current flow in the windings, resulting in better efficiency and longevity. |
| Closed Loop Control System |
A control system where the output is fed back to the input for continuous monitoring and adjustment. |
| Controller |
The component of a control system that calculates the necessary adjustments to minimize the error signal. |
| Derivative |
A control strategy where control output is proportional to the rate of change of the error signal. |
| Electrical Actuator |
A device that converts electrical energy into mechanical energy to produce linear or rotary motion. |
| Error |
The difference between the desired value and the actual value of the controlled variable. |
| Error Signal |
The difference between the reference input and the actual output of a control system. |
| Feedback |
Information about the system's output that is used to adjust the system's input. |
| Integral Control |
A control strategy that accumulates the error signal over time to eliminate steady-state errors. |
| Linear Actuator |
An electrical actuator that produces linear motion, often used in applications such as robotics or automation systems. |
| Open Loop Control System |
A control system where the output is not fed back to the input. |
| PID Control |
A control algorithm that adjusts the output based on the proportional, integral, and derivative terms. |
| Piezoelectric Actuator |
A type of actuator that uses the piezoelectric effect to generate motion when an electric field is applied. |
| Proportional Control |
A control strategy where the controller's output is proportional to the error signal. |
| Pulse Width Modulation |
A technique used to control the position of a servo motor by varying the width of electrical pulses. |
| Reference Input |
The desired value or setpoint that a control system tries to achieve. |
| Sensor |
A device that measures a physical quantity and converts it into an electrical signal for the control system. |
| Servo Motor |
A motor that operates as a closed-loop system, using feedback to control the position, speed, and torque accurately. |
| Setpoint |
The desired value or target value that the system aims to achieve. |
| Solenoid |
An electromagnetic device that uses a coil of wire to generate a magnetic field, which in turn produces mechanical motion. |
| Stepper Motor |
A type of electrical actuator that moves in discrete steps, based on digital pulses, allowing for precise control. |
