ECS

The paper deals with features of designing high-precision systems for stabilization and determination of attitude and heading reference systems. Features of the parametrical optimization are considered. The necessity to use the robust control laws is grounded. The mathematical model of the studied system in the preliminary levelling mode is represented. Simulink model of the navigation loop is shown. The necessity and features of the model’s linearization are explained, Basic concepts of creating models directed for solution of the studied problem are represented. The design process is considered on the example of the precision gimballed navigation system assigned for operation on marine vehicles. The proposed approach to problem solution is accompanied with simulation. The simulation results prove efficiency of the described design procedure. The obtained results can be useful for creating stabilization and motion control systems of the wide class.

“…Possibilities of application of excessive measurement devices in fault-tolerant navigation systems are investigated in [10]. Using the redundancy of inertial meters (accelerometers), it is even possible to determine the spatial orientation of a moving object without the use of high-speed rate gyros, as it is represented in [11]. Sometimes redundant measurement data arises in accordance with the principle of operating the navigation meter.…”

The non-collinear measurement devices based on the inertial triaxial devices, and structural units such as the triangular, and quadrangular polyhedrons are presented. The corresponding matrices of guide cosines are obtained. In contrast to the known non-collinear measurement devices, the measurements of all sensors that are part of the triaxial devices are taken into account. A description of the relative position of the measurement axes of the individual sensors in the proposed measurement devices is given. Theoretical estimation of non-collinear measurement devices of MEMS-sensors on the basis of uniaxial and triaxial angular velocity meters using correlation matrices of measurement errors is obtained. The obtained results are useful because they are aimed at providing high-precision and reliable measurements that is important for unmanned aerial vehicles, which are currently widely used in Ukraine.
