Wavelet-based technique for feedback control of uncertain systems — A case study

In designing control systems an important aim is minimizing the effects of uncertainties on system performance. The time-frequency characteristics of wavelets are useful for applications that require online response, such as controlling a process. It is proven, that the wavelet based controllers perform extremely well under certain definite conditions. In this paper, the multiscale representation of the error signal is investigated in direct feedback. The control method is applied to a temperature control task. Simulation results show satisfactory performance and highly efficient disturbance rejection. Advantages and drawbacks of the wavelet based control strategy are also discussed.
