Abstract :
Due to the structural coupling of a space shuttle vehicle, the selection of a suitable controller gain has been a difficult task. However, this task is very critical as it will affect the performance of the controller. In this brief, a band-stop filter is constructed by using a combined network of a low-pass filter and a high-pass filter. On this basis, digital processing is carried out using bilinear transformation and predistorted processing. To solve the parameters of the filter, a frequency-domain method and an optimization method are applied. The designed filter can effectively reduce the structural coupling, as well as broaden the margin for the regulation of the control law.
