Abstract
The interval-multiplex approach was applied to controlling the orientation of an artificial satellite under incomplete information about its state vector. When estimating the state vector, use was made of additional restrictions on the values of inaccuracy of measurements. Instead of linearizing the nonlinear system at the single point corresponding to the orientation mode, the linearization is carried out at each step, at the points representing the estimates of the state vector. Computer simulation demonstrates the effectiveness of using additional restrictions.
