What Exactly Is Motion Control?

What Exactly Is Motion Control?
A subsystem of an industry automation system is motion control. To complete a sequence of movements, it synchronizes and regulates numerous motors. A multi-axis robotic arm, for example, requires a lot of motors to work in unison to execute a given maneuver. Motion control is mostly utilized for trajectory planning, speed planning, interpolation, and kinematics conversion. Motion control systems are commonly used in printing, packing, and assembly.

A motion control system typically comprises of the following major components, as illustrated below:

A motion controller that generates trajectory planning before sending control orders to motor drivers.
Motor drivers transform motion controller control commands (typically a speed or torque signal) into a higher power voltage or current signal to drive the motors.

Motors that move in response to control commands
Position sensors that send position/speed data from the motor rotor to the position/speed controller in order to accomplish precise position/speed control.

Motion Control versus Motor Control
Motor control, on the other hand, is a method or technique that is primarily focused on controlling the motor's spinning. A typical motor control system modifies one or more of the torque, speed, and position parameters of a single motor to achieve the desired values. The requirements and strategies for driving a motor might vary substantially depending on its type. A motor controller often lacks planning capabilities; sophisticated drivers can only plan for position and speed. As a result, the following is a straightforward explanation of the distinction between motor control and motion control.
Given the distinctions between the two systems, it is evident that the design needs or resources for both are also considerably different.
