A scheme for globally stabilized controller design was proposed based on stability criterion of density function and solved via SOS (sum of squares) decomposition tool. In order to deduce the complexity of the controller, it was designed with minimum monomial terms which approximated by minimizing the norm 1 coefficients of controller monomials. Guaranteed convergence rate performance was considered...
Aiming at the properties of the object of the hybrid system, the modeling method based on the mixed logic dynamical (MLD) model has been introduced, the continuous dynamic process and the discrete dynamic process in the hybrid system are expressed into state space equations with mixed-integer inequality constraints. Through the enlargement of the classical generalized predictive control (GPC)'s object,...
To ensure the long-term on-orbit working precision of attitude sensors, a new approach for the high-precision three-axis stabilized satellite with the typical inertial/stellar measurement mode is presented. This approach employs a real-time on-orbit calibration system to estimate the measurement error of gyro by star sensor. The calibration system is achieved by using a second-order nonlinear filter...
