带摆动机构的多线切割机的线性H_∞张力控制
The linear H-infinity tension control of multi-wire saw with rocking mechanism
摘要
Abstract
To deal with the low control precision and the nonlinear interference in the normal control of a multi-wire saw with rocking mechanism,a linear H-infinity control algorithm with disturbance observer is proposed.The algorithm gives a solving project in considering both errors caused by dynamic disturbances of the subsystem model and unmodeled dynamic disturbances,along with the uncertainties in parameters and the structure of the multi-wire saw with rocking mechanism.The stability of linear H-infinity control systems is studied;and under the conditions of the system stability,the analytical solution of dynamic equation is obtained by using the method of Chelosky decomposition.The speed of system response is improved significantly.Experimental results on a model machine show a small tension variation,a desirable stability performance and a low value of the break line ratio.关键词
