ASVG Digital Controller Design Based on Polynomial Pole Allocation

A digital controller design method for ASVG based on polynomial pole allocation 7is proposed.The method is a mathematical model based on d-q coordinate system,the design is a double-loop digital controller and the internal loop of the current is two free degree controllers,which start with the time domain performance index to build the ideal internal loop characteristic polynmial using polynomial pole allocation.The command current and the current disturbance are separately controlled.The system has fine tracking performance,anti-interference performance and fine robustness.For the outer loop of the voltage,according to the time-domain performance index to build ideal outer loop closed loopcharacteristic polynomial through polynomial method pole allocation.Set the controller which has a specific link make the system have fine anti-interference and reduce measurement error.The results show that the controller according to the method proposed can make the voltage of the DC side stable and interference elimination have fine current tracking performance.
