| Abstract | This work discusses and simulates the discrete-time control of artificial satellites with flexible appendages, and its stability in function of growing sampling periods. Due to mission needs the dimensions of the appendages tend to increase becoming more flexible. As a result, it is important to investigate the effects of digital characteristics such as sampling period, delays (in inputs, processing and outputs) and amplitude quantization on it. In this work only the sampling period effects are investigated. The discrete-time PD controller design is done considering aspects such as the aliasing and the hidden oscillations. It is tested with models of an harmonic oscillator and of the CBERS1(China-Brazil Earth Resources Satellite), comparing the analog PD with discrete-time PDs obtained by standard s-z mappings (Tustin and Schneider) and by a new mapping, using the same gains for them. Root-loci, transient and steady-state responses were used to analyze their performances. These suggest partial methods of stabilization; and that the new mapping has the best performance among the mappings tested. | |||
