Servo systems are automatic control systems used to perform speed, position, and sometimes torque control of motors. These systems are commonly used in applications that require precise motion control. There are two main types of control in servo systems: speed control and position control.

Speed control: Speed control aims to maintain the rotation speed of a motor at a specific value. The servo drive adjusts the motor's speed using feedback from speed sensors (usually encoders) and increases or decreases the motor's speed until the desired speed is reached. Speed control is important in applications that require continuous motion, such as conveyor systems, pump systems, or fans.

Position control: Position control enables the motor to move accurately and precisely to a specific position. The servo drive calculates the difference between the motor's current position and the target position using feedback from position sensors (usually encoders). It then adjusts the motor's motion until the target position is reached. Position control is important in applications that require precise positioning, such as robotic systems, CNC machines, or automated assembly systems.

Servo systems provide both speed and position control, offering high performance in applications that require precise motion and positioning. These systems are commonly used in industrial automation and robotics applications that require high-speed and precise motion.
