Speed Control Application with PLC High Speed Outputs Port
Since the first MODICON 084 PLC, their performances have been continuously improved. Today, there are PLCs whose digital outputs can be configured as high-speed outputs. In this paper a closed-loop control application that allows testing the PLC high speed outputs port configured to generate PWM signals is presented. The application consists in controlling of the angular position of a balance using two brushless motors kits for drones attached at the ends of the balance. The speed of each brushless motor can be adjusted with a servo PWM signal with period equal to 20 ms and the pulse width between 1 ms and 2 ms. The proposed solution can be used by students or specialists for training because it offers an experience closer to the realworld applications.
