Local vector control of an AC drive system load simulator

This paper describes the application of the local vector (LV) nonlinear control strategy to a load simulator for an AC drive system. The load simulator physically consists of a computer controlled DC machine which is connected to the AC machine under test by a rigid shaft. With appropriate control the DC machine load is able to simulate static loads. First order dynamic loads (i.e. loads with varying J, f), and second order dynamic loads (i.e. rotating loads connected to the test machine via a compliant shaft). This paper presents SIMULINK simulations of the proposed control system and discusses some implementation issues
