This paper considers a hybrid optimization control problem by mixing the low and impulsive (high) thrusts, which is a continuous and fixed-time interval control strategy for impulsive control of the orbit interception correction. Initially the linear system model is established and linearized by two-body equations of motion. The hybrid linear control system is analyzed and control law is obtained...
Despite significant progress in the optimal theory of impulsive control systems, finding the optimal solution for them still remains a challenging task because of the computational complexity. In this paper, we focus our interests on the LQ-based optimization for a specific class of linear impulsive control systems mixed with continuous-time controls and fixed-time impulses so that the problem-solving...
A hybrid filtering approach is proposed for satellite attitude determination, which may furnish an optimal estimate of the state vector in the case where the measuring systems are composed of dissimilar types of multi-sensors with different sampling frequencies. Obviously, the no uniform sampling may be regarded as its special case. Then, a six-dimensional state error equation for satellite attitude...
