查询词典 pole

Single loop instantaneous voltage feedback control and multiple loop feedback control, which can be realized by digital method or analogue method, are normal control strategies of inverter. The controller's performance of a same control strategy designed by different designers is different This paper makes out uniform analysis and design theory of inverter control strategies with pole-assignment technique of state-space theory for the first time. It is firstly proposed that controller parameters being equal to control system orders is the base of realizing high performance inverter. Design and performance comparability of various controllers is presented with uniform pole-assignment method.
