Diseño e implementación de un módulo didáctico para el control de velocidad en lazo abierto de un motor de corriente continua

Abstract

In the present project a system for the electronic speed control of a direct current motor is implemented through 4 types of controls: direct phase, chopper, reverse phase and integral cycle. For this, the system has a synchronization circuit with the network to emit a pulse each time the input voltage passes through zero in the direct and inverse phase control, a power circuit for the AC / DC conversion of the signal input and where a mosfet is triggered through the PWM signal delivered by the microcontroller to generate the trigger angle with which the motor speed is varied, a control circuit that is based on a Master-Slave system through 2 microcontrollers that are programmed to regulate the behavior of the entire system, here they load and execute all the instructions to be made, in addition, another circuit with two different continuous voltage sources is required for the power supply of the electronic devices used . All the circuits are distributed in 3 electronic boards and a linearization system was inserted for the best performance of the motor.
