A new control strategy based on feedback motion planning is presented for solving nonlinear control problems in constrained environments. The algorithm explores the state-space using a bi-directional rapidly exploring random tree (biRRT) in order to find a feasible trajectory between an initial and goal state. By incrementally scheduling LQR controllers, it attempts to connect states so as to link...
Multiparametric quadratic programming (MPQP) can be used to construct an off-line solution to constrained linear model predictive control. The result is a piecewise linear state feedback defined over polyhedral cells of the state space. However, with high dimensional problems, coding and implementation of this solution may be very burdensome for the available hardware, due to the high number of polyhedral...
Aiming at time constraint and trajectory phase angle constraint of aeroassisted space rendezvous, a approach guidance method belonging to the nominal guidance was presented. Due to initial trajectory errors and external disturbances existing in atmospheric flight, linear quadratic regulator was designed and computation method of weighted coefficient matrixes was given. Mathematic simulation example...
