Min–max fractional quadratic problemsConic reformulationsCopositive coneCompletely positive coneLower boundsIn this paper we address a min鈥搈ax problem of fractional quadratic (not necessarily convex) over linear functions on a feasible set described by linear and (not necessarily convex) quadratic ...
This brief shows how a min–max MPC with bounded additive uncertainties and a quadratic cost function results in a piecewise affine and continuous control law. Proofs based on properties of the cost function and the optimization problem are given. The boundaries of the regions in which the state...
Variational principles are very powerful tools when studying self-adjoint linear operators on a Hilbert space \\(\\mathcal{H}\\) . Bounds for eigenvalues, comparison theorems, interlacing results and monotonicity of eigenvalues can be... H Voss - Enumath 被引量: 8发表: 2013年 Quadratic Hyperb...

A simulation example is given in the paper. Introduction In Min-Max MPC controllers [2], [1], the value of the control signal to be applied is found by minimizing the worst case of a performance index (usually quadratic) which is in turn computed by maximizing over the possible expected ...
iteration. After fixed number of iterations (or after model breakdown) we recalculate quadratic model using analytic Jacobian or finite differences. Number of secant-based iterations depends on optimization settings: about 3 iterations - when we have analytic Jacobian, up to 2*N ...
