CONTROLLER FOR DYNAMIC SIMULATOR

摘要

PURPOSE:To maintain the inertia on the side of a prime mover at a constant level over a wide frequency band in a dynamic simulator to be employed in a simulated load of the prime mover. CONSTITUTION:An observer 502 is designed so that it estimates the driving torque of a prime mover and n-th differentiated value thereof. Based on an output from the observer 502 and an axial torque command tau* passed through a filter 503, an inertia compensation torque command tauM* is created through a feedback gain K. The torque command tauM* is then added to the axial torque command taua* to produce a torque command taua* for a generator. Consequently, inertia on the side of the prime mover is controlled at a constant value over a wide area by setting the transfer characteristics of the observer 502 and the filter 503 and regulating the feedback gain K.
