Observer-Based Mixed ℋ2ℋ∞ Tracking Control for Continuous-Time Systems with Integral Action and Pole Placement

الملخص EN

The tracking problem for continuous-time systems is investigated.

It is assumed that the states of the systems are not available.

An observer is firstly designed to estimate the states by using the ℋ∞ method.

The control action is consist of a state-feedback control, an integral component, and a feedforward loop.

The linear-matrix-inequality region is used to constrain the eigenvalue location for the closed-loop systems.

The control gains can be obtained by solving a sequence of linear matrix inequalities (LMIs) which can guarantee the mixed ℋ2/ℋ∞ performance for the closed-loop systems.
