The optimal output tracking control(OOTC)problem for a class of bilinear systems is considered where the reference input is described by an exosystem.

According to system characteristics of the system, optimal tracking control is applied to exact linearization and nonlinear control law is obtained.

Dynamic equations of a 3 degree-of-freedom model for the multi-axle steering system of the truck-howitzer including the vehicle body side-sway characteristic was derived,a dimension reduction observer for rebuilding the vehicle state was constructed,and a vehicle steering controller based on the optimal tracking strategy was designed.

The design problem to achieve the optimal tracking controller which satisfy the specific optimal dynamic performances for a MIMO linear discrete_time system with some specified inputs is converted to a linear programming problem with finite variables.

Asymptotic output tracking of affine nonlinear singular control systems;

A Tagaki-Sugeno(T-S) fuzzy model approach is presented for tracking control of the reliable H_∞ output tracking control in a class of nonlinear descriptor system.

The optimal output tracking(OOT) problem for a class of nonlinear time-delay systems is considered where the reference input and the external disturbance are described by the exosystems.
