In this thesis,we propose a general procedure for developing
Spice macro models of electrical$-$mechanical systems. We also
employ these models in designing an elevator system. The
details of the design of the general elevators are reviewed in
this thesis. Several DC and AC motors have been equivalently
transformed to macro$-$circuits which simulate both the
electrical and mechanical characteristics of the motors. The
vector$-$control theorems are employed in designing the
elevator system which includes a three$-$phase induction motor,
a PWM driving power inverter, a coordinate$-$transformation
function, and the associated controllers. The design steps for
this system, including the steps to simplify the induction
motor model by using the coordinate transformation are showen
inside. The~Spice~experiment results have showen good
performance for the speed profile control of the elevator
system designed here.
