This work presents the implementation of a conventional PID and a fuzzy PI control schemes in a 16 bits microcontroller. These schemes are designed for the speed control of a DC brush motor. This article makes emphasis in the handling of the floating point for the first case. For the fuzzy control, the data is obtained directly from the digital analogical converter of the system.
The paper presented the double switched reluctance motors parallel drive system for the electrical traction in shearer. The system components, such as the switched reluctance motor, the main circuit of the power converter and the controller, were described. The control strategies of the closed-loop rotor speed control with PI algorithm and balancing the distribution of the loads with fuzzy logic algorithm...
