On the robustness of LQ regulators
IEEE Transactions on Automatic Control, 1984Summary: It is shown that in spite of its large gain and phase margins the linear quadratic state feedback regulator may suffer from poor robustness where small changes in the parameters of the system may lead to fast unstable closed-loop modes.

On the utopian approach to the multiobjective LQ problem
Optimal Control Applications and Methods, 1993AbstractThe infinite horizon, multiobjective linear quadratic control problem for continuous time systems is considered. Following a utopian approach, the optimal solution is defined as the solution that minimizes the distance from the utopian point in the cost space.

The parametric linear quadratic (PLQ) control problem is considered for discrete-time stochastic systems. The control problem consists of a non-linear optimization problem in the parameters of a linear regulator. Results on global convergence and on rate of convergence are given for the linear-descent mapping method for solving the optimal regulator ...

Conditions on the powers p, q and dimension of the space, n, are given so that. if they are satisfied, then the lp -L,-estimates hold for the solution of the Cauchy problem for the second order hyperbolic equa??tions with constant coefficients.
