OPTIMAL CONTROL OF THE PIEZO ACTUATOR FOR TUNING THE RADIO-REFLECTING MESH OF SPACE REFLECTOR
Annotation
The process of controlling a piezo actuator for adjusting the shape of radio-reflecting mesh of a large-sized transformable space-based reflector is considered. A point-by-point adjustment scheme is selected. Due to the limited supply of electrical energy on board the spacecraft, the control problem is solved with the account for energy costs in real time. An algorithm has been developed for sequential control optimization for automatic cable length adjustment using a piezo actuator. The algorithm allows minimizing energy costs and fulfilling terminal conditions with high accuracy. By choosing the weighting factors, the best version of the control program is determined for different finite simulation times. The flexibility of the developed algorithm is shown when choosing the optimization criteria.
