摘要
Abstract
In this paper ,the sampling H ∞ control scheme is presented for a permanent magnet synchronous motor (PMSM ) servo system .The sampling closed-loop system is established based on the sampling state feedback controller for the PMSM servo system .The definition of sampling H ∞ performance is also given .In order to solve the problem of the sam-pling H ∞ control ,the sampling closed-loop system is transformed into a continuous system by the time delay method .Then , the existence conditions of the controller are derived based on linear matrix inequality (LMI) technology .Simulation results show that the proposed control scheme makes the rotational speed of the PMSM track the reference value quickly in the case of parameter variant and load disturbance .It also has the characteristics such as fast response ,better stability and strong ro-bust .关键词
