Resumen
Descripción general del contenido del recurso.
New solutions for two permanent magnet AC machines control issues are proposed in this thesis. These issues are: ripple torque minimization and elimination of mechanical speed and/or position sensors. In order to minimize the ripple torque that is produced by neither sinusoidal nor trapezoidal induced emf, a new current control technique is proposed. The proposal is based on vector control ideas, and it allows to perform the current control in DC variables, in the same way as in sinusoidal PM machines. Two new reduced-order state-observer based strategies are proposed with the aim of eliminating position and/or speed sensor, for the control of arbitrary emf waveform machines. The proposals allow the estimation of machine induced emf. Rotor speed and/or position can be obtained from the estimated emf. One of the proposals includes a Fourier series approximation of the induced emf waveform that allows the modeling of machines with any emf waveform. The second one employs a reduced order observer combined with a high gain observer. In addition, a state vector extension is proposed for load torque estimation, in order to compensate the perturbations produced by the unknown load. The most important contribution of this work is the use of observers that are not limited only to sinusoidal or trapezoidal emf machines. Simulation and experimental results that validate the proposed strategies are presented.
