... regulator framework. Preview regulation is accomplished by a two-degrees-of-freedom output-feedback controller. A number of theoretical issues are studied, including the efficient solution of the standard H 2 full-information Riccati equation and the efficient evaluation of the full-information preview gain...

... of the mill that overcomes many limitations of the present controllers. The new strategy is based on a pointwise linear quadratic technique wherein a state-dependent algebraic Riccati equation is solved pointwise to establish a control law for a multiinput–multioutput controller, with appropriate trimming...

... in the stabilization of the total system, the internal forces are considered to be reduced by the nonlinear regulation based on a State-Dependent Riccati Equation (SDRE), where the internal forces are derived by a projection method. The dynamics of individual components and the relations of the constraint motions...

... is based on the realization that the dynamics of input shaped systems give rise to time delays in the input. Thus, we exploit the feedback control theory of time delay systems for the closed-loop control of input shaped flexible structures. A Riccati equation-based and a linear matrix inequality-based...

.... For testing the system stability, we do not attempt to solve the Lyapunov or Riccati equation, but need only to check the eigenvalues of a Hamiltonian matrix to guarantee the solvability of an algebraic Riccati equation. The present method is simple and less conservative than those proposed in the literature...

The results obtained are valid for steady state. In that direction, the corresponding algebraic filter Riccati equation is completely decoupled...
