The Internal Model Control Based On Inverse System Method And Researched In The Low Speed Problem Of Servo System

The main factor, which affects the performance of servo system inthe low speed range, is the nonlinear friction. Thus it affects theperformance targets of track system in the low speed range. So the servosystem low velocity problem is one of the main research domains. In this paper, the internal model control method based on inversesystem method is researched. And track performance and anti-jammingperformance of one-degree-of-freedom and two-degree-of-freedom of theinternal model control based on inverse system method have been analyzeddeeply. And a lot of simulations have made. Based on feasibility and validity of the theory through the simulations,the internal model control based on inverse system method is proposed tosolve the problems of servo system in the low speed range. There are gooddynamic track results and good performance. The control method have abetter performance of servo system in the low speed range compared with III北京化工大学学位论文the neural network compensation method . In this paper, anti-jammingperformance of the control system has been tested.
