Power processor fed induction motor for simulation of internal combustion engine

A high performance electric drive system was developed to simulate the operating characteristics of automotive internal combust1on eng1nes. The torque-speed profiles of various types of automotive engines are stored on a printed circu1t card, thus allowing a particular engine to be selected simply by pushing a button. Th1s system has been used for both production testing and engineering analysis of automatic transmissions. The method of generating the torque-speed curves and the basic feedback control system are described.
