Direct adaptive fuzzy predictive control of flexible structure based on characteristiC model
基于特征模型的柔性结构直接自适应模糊预测控制

To avoid the overflow of the control and observation caused by using mode truncation to design controller,the flexible structure model is transformed into the characteristic model described by a second-order difference equation with unknown coefficients,then a direct adaptive fuzzy predictive control method is presented for the flexible structure position holding.In this method,a fuzzy logic system is used to design predictive controller directly,both the controller parameters and the unknown vectors in the estimation of generalized error are adjusted adaptively.It is proved that the designed controller can make the estimation of generalized error converge to a small neighborhood of the origin.Simulation results demonstrate the effectiveness of this method.
