Position synchronization and speed control of linear electric operators using the PSO optimized PID controller

The widespread use of electric motors makes engineers careful in designing, operating and controlling electric motors, so that such a device, which is used by even the most common people, can be easily exploited. And meet the different needs of a community. Rapid control and switching of these motors is also of paramount importance in varying conditions and often in the shortest possible time. Obviously, in any design, the need for economical and environmental dimensions and weight restrictions must also be taken into account. Control systems should have the following characteristics: absolute and relative stability, accuracy, speed, and cost. There are many control methods for doing this research: PID controllers, fuzzy logic, neural networks, optimization algorithms, or combinatorial methods, each of which, depending on the desired operating conditions and capabilities, can perform better than the other methods. The importance of selecting a control system is appropriate to the conditions in the synchronization of linear electric actuators. Synchronization control of the position of linear electric operators is very important because it can be used in industrial, home, medical, agricultural, robotics and other applications In this research, we will examine the position, speed and job security of two linear actuators with encoder DC motors synchronously and control PID and PID-PSO methods are considered and compared.
