This report describes the outline and its application example of simulator "SIGMA" developed at Toyohashi University of Technology. "SIGMA" has the excellent man-machine interface alike to that of analog computer where the wiring of operational element through graphic display is only required. As many kinds of elements are available and user can define the function of the element in FORTRAN, "SIGMA" can simulate complicated system including non-linear elements with a personal computer, which were conventionally carried out with a large-capacity computer. To examine the applicability of "SIGMA", the report analyzes the behavior of reciprocating compressor system driven by the vector-controlled induction motor. Each operational element was used to model the inverter with complicated switchig operation, the induction motor which was transiently subjected to magnetic saturation, and the mechanical system which was accompanied by torsional vibration. The model prepared can properly express the behavior of actual reciprocating compressor system in which the motor current and rotating speed of the motor are fluctuated together with the load fluctuation. The simulation using "SIGMA" can be applied in substitute for actual machine test.
