Poles and Zeros
In Part I, we have discussed various topics relevant to electromechanics which is the study of energy interaction between electrical and mechanical components. We demonstrated that the dynamics of complex electromechanical systems can be best understood by identifying the interaction between various energy storage and energy dissipation elements, some of which can be purely electrical (capacitance, inductance, resistance), some purely mechanical (compliance, inertia, damping), and some are in fact electromechanical (magnetic and piezoelectric coupling, etc.). In Part II, we shall discuss various topics related to contromechanics which is the study of energy interaction between control and electromechanical components. The purpose of control, as we have mentioned already, is to enhance the performance of the electromechanical systems.
