The design of observer based tracking control for weakly nonlinear systems using differential matrix equations Riccati

The paper deals with finite-horizon tracking control problem for a class of weakly nonlinear systems with statedependent coefficients. Synthesis of control and the state observer is carried out on the basis of an approximate solution of the corresponding differential matrix Riccati equations using the same numerical-analytical procedure. The advantage of this approach is the reduction in computational complexity. Numerical experiments showed the efficiency of the proposed control algorithm.
