Did You Know the Mechanism behind Motion Control?
Motion control is a technology by which machines are automatically controlled either directly by humans or by robots via sensors, numerical patterns or by computer. This is also known as automation. There are multiple control mechanisms for operating such a system.
In the case of computerized motion controllers, there are several components to perform the same. These are like application software, amplifier or drive, motor, mechanical elements, feedback sensors. The software is used to command via computer or any such device. The motion controller acts as both a catalyst as well as a resistance. The amplifier receives the command to generate the required electricity. The motor helps to move along the targeted space or position.
In various fields, the motion required also varies. That is why several profiles in a system to control the motion are set up. This is known as prototyping. It helps to provide the desired or required amount of mechanical motion in multiple phases.
The working principle or mechanism of the Motion Control
A motion controller is like a human brain. As our brain controls our whole body, so does the controller. It controls the motion system by perfectly calculating each command and target. Most of the motion systems are done via digital signaling. And finally, it causes the whole motion as required.
For constant and better operation, the controller always needs to close the loop in case of any emergency. It also supervises the motion limits. The motion trajectory sends the controller commands via signals. It allows the amplifier to start the motor as per the prototype by converting the analog voltage signals of low current into digital signals of high current. For proper output, the controller measures the desired target position, calculates maximum velocity and acceleration.
There are multiple types of motion movements:
- Contoured Motion
- Coordinated Multiaxis Motion
- Blended Motion
- Point-To-Point Motion
- Electronic Gearing, Etc.
Despite automation, some companies also make their custom motion controller for high-precision output. But this fixed prototypical profile of the controller is not flexible to be redesigned for variations in controlling the motion in the future.
Automation has been in top use today in various ways including electrical, hydraulic and computerized systems. In factories, airplanes, and ships as well as inexpensive cars this has become an easily available facility. Its benefits include savings of labor material electricity. It also provides updated accuracy and desired output with high-precision.
