| Summary: | Understanding the dynamic behavior of electric motor drives is neither easy nor obvious. Indeed, there is no unified approach to model both the mechanical and the electrical elements of the motor drive while representing each of these elements for what it actually stands for. Currently available modeling methods fail to overcome the electro-mechanical conversion and therefore to bring one model for the whole drive that brings an intuitive understanding of the dynamic behavior. The problem becomes even trickier for AC drives where the analysis has to take into account AC variables. At this day no method has been proposed to overcome the inverter and model the drive from an external point of view. In this thesis, the electrical analogy theory and the generalized impedance converter theory are presented. A method is developed that uses both these theories to model DC motor drives and explain in a deep yet easy and obvious manner their dynamic behavior. The method is then expanded and applied to vector controlled sinusoidal synchronous motor drives. The method allows understanding some aspects of the dynamic behavior of motor drives such as the interaction between electric inductances (armature or filtering) and the rotor inertia, the rather oscillating behavior during field weakening operation, and low or high duty cycles. |
