The experimental results obtained in the design and implementation of an decoupled digital speed and voltage controller for a micro-energy system are reported in this work. The studied system is formed by a 9Kw DC motor driving a 10KVA synchronous machine. There are two control loops in the proposed controller: the speed control (Speed Governor) and the control of the stator's voltage (Automatic Voltage Regulator). Each control loop was designed using linear control techniques and Fuzzy control techniques. Tests on the system show the performance of the proposed controllers.
