The Aerospace Unit has participated in the development of the SALITRE project for the Cantabrian Company ACORDE Technologies. The objective of the stabilized platform is to provide with satellite communications to a vehicle in movement. These are mainly used in high performance applications. In this case, the main contribution of CTC has been the development of a high performance control unit that confers an important improvement to the system precision. The following video shows the high dynamic performance of the developed system.
The special characteristics of this new system, as well as the recent acquisition of new equipment, ACUTRONIC 2-axis motion simulator, have permitted to carry out Hardware-In-the-Loop (HIL) laboratory tests. This is the first occasion when the Centre has the opportunity to carry out laboratory tests over a stabilized platform complete system. The main advantage of this type of simulation is that it allows shorting the systems development time and facilitating the design. This is possible by simulating real operating conditions in a controlled laboratory environment, and subjecting to testing the whole system, both hardware and software and control algorithms.
One of the HIL test procedures is shown in the above video. It consists in subjecting the inertial sensors of the system, which are used for measuring the attitude changes of the platform, to controlled disturbances and then monitoring the actual output of the control system (position and velocity of the axes of the antenna’s positioner).
