摘要：
In this paper, a Wavelet Controller analogous to a Proportional-Integral-Derivative controller is proposed. The control strategy is based on the multi-resolution decomposition of error signal using Wavelet Transforms. The output from a system represents the cumulative effect of many underlying phenomena such as process dynamics, measurement noise, effects of external disturbances etc., which manifest on different scales. The wavelet decomposition, which represents the error signal at different scales, enables us to compensate for these uncertainties in the control design. Simulation results are shown to validate the control strategy.
