Novel self-adjustable grey prediction controller

Traditional feedback control and grey prediction control are integrated together to build a novel self-adjustable grey prediction controller. The current output error and the predicted output error are combined together to form an integrated error. In the proposed control scheme, the error item in the traditional feedback control is substituted by the integrated error so that the controller can calculate the control law according to both the current output and future output. Furthermore, This controller can automatically adjust controller parameters according to the precision of grey prediction, which makes the controller adaptive to the response of systems. Simulation results show that this controller can achieve better dynamic performance and robustness than traditional feedback control.
