Motion controllers are widely used in many fields, especially in AC servo and multi-axis control systems. They can make full use of computing resources, help users plan trajectories, execute predetermined actions, and perform high-precision servo control.
The development of motion control technology is a driving force behind manufacturing automation and a key technology propelling the new industrial revolution. Motion control typically refers to the conversion of predefined control systems and design instructions into desired mechanical motion under complex conditions to achieve precise position, speed, acceleration, torque, or force control. This article collects and gathers information on what kind of business supervisors and what kind of tax return forms can be used.
A motion controller is a special type of controller used to control the operating modes of a motor. For example, a motor might be pulled to a designated position and then lowered by an AC contactor controlled by an impulse switch, or its forward and backward rotation might be controlled by a time relay, or it might pause briefly before stopping again. The application of motion control in robotics and CNC machine tools is more complex than in dedicated machine tools because the latter have simpler motion patterns and are often referred to as general-purpose motion control.
Depending on the energy source, motion control can be mainly divided into electric motion control (using electric motors), gas-liquid control (using gases and liquids), and thermoelectric control (using fuels such as coal and oil). Statistics show that over 90% of electricity comes from electric motors. Electric motors play a vital role in modern production and daily life; therefore, electric motion control is the most commonly used type of motion controller.
Electronic motion control evolved from the use of electric motors, with electric motors being a general term for control systems based on them. There are many types of motion control systems, but from a basic perspective, a typical modern motion control system mainly consists of a supercomputer, a motion controller, a power drive, a motor, actuators, and a motion controller feedback device. The motion controller is a control unit, its core being a central control unit. Its sensor is a signal detection element, and its motor or drive unit and performance unit are the controller components.
Motion controller control form
Point-to-point motion control:
In other words, achieving the desired position requires only one thing, regardless of the intermediate processes or trajectories. A suitable motion controller should quickly determine the velocity and apply various acceleration and deceleration control strategies during the acceleration and deceleration phases of the motion.
At a set speed during rapid acceleration of the system, the system's rigidity and acceleration are typically increased, and an S-curve deceleration adjustment is applied at the end of deceleration. To avoid vibration after system installation, the system's advantages are correspondingly reduced in the design. Therefore, point motion controllers typically have the ability to control changes in parameters and deceleration curves within the control network.
Continuous motion control of paper rolling:
This type of control, also known as contour control, is primarily used for motion contour control in traditional CNC and cutting systems. The corresponding motion controller must address how to ensure the accuracy of the system's contour modifications and how to maintain a constant tangential speed when the tool moves at high speed along the contour. For processing small segments, the program has several preprocessing functions.
Synchronous motion control:
Multi-axis cooperative motion control can synchronize multiple axes throughout the entire motion process or achieve localized speed synchronization. Primarily used for system control, it requires electronic transmission and electronic control functions. Industries using this technology include dyeing, printing, papermaking, steel rolling, and synchronous cutting. Adaptive power control is commonly used in the control algorithms of corresponding motion controllers. By automatically adjusting the amplitude and phase of the control variables, it ensures that the increased output control function has the same amplitude as the disturbance but opposite phase, eliminating periodic disturbances and ensuring synchronous control of the system.
In other words, motion controllers are widely used in many fields, especially in AC servo and multi-axis control systems. They can fully utilize computer resources, facilitating motion path planning, executing predetermined actions, and achieving high-precision servo control. The combination of motion control technology and AC servo drive technology has driven the continuous development of electromechanical technology in my country.
