This work deals with vector control applied to the three phase induction motor (IM), using the indirect field oriented control (IFOC) technique. In the proposed topology, sliding mode controller with chattering reduction is applied, aiming high dynamic performance in a wide speed range and robust to load disturbances. Therefore, an approach with soft switching hyperbolic tangent function on the controllers...
This work describes the development of a heading reference system composed of low cost inertial sensors with MicroElectroMechanical Systems (MEMS) technology, which present high noise levels. Thus, filtering and sensor's measurements fusion is done in order to achieve a reliable estimation, trough an extended Kaiman filter. The system is used for navigation and control of an autonomous aquatic surface...
