Abstract

Aiming at stochastic discrete linear system with bounded disturbance,a finite-horizon receding predictive state feedback control with recursive form was proposed by constructing a close formation for stochastic predictive cost function and using the stochastic minimum principle.A continuous predictive control algorithm was proposed by continuous approximation method,which was applied in guidance law.In order to avoid two-point boundary value problem and computation burden,an approximative guidance law algorithm was deduced.The simulation result shows that the guidance law has trajectory prediction function;the guidance law has smaller overload in the ending phase of trajectory compared with PNG and SPN.
