The CMAC tuning effects to improve the H∞ control performance

摘要

The CMAC tuning effects to improve the H∞ control performance is proposed in this paper. The H∞ norm is utilized for evaluating the supremum of the robust control variable such that it ensures the Lyapunov stability of the proposed control schemes. Under the Lyapunov stable criterion, we apply the novel pre-step CMAC online tuning scheme for tuning the control variable in order to improve the system output performance. Two kinds control schemes are employed to simulate and discuss in this paper: the supervisory robust control and the pre-step CMAC robust control schemes. Finally, simulation results demonstrate that the pre-step CMAC robust tuning control schemes can efficiently save control power and decrease control error, which make the system output follow the control command quickly and accurately.
