LQ Regulator by Lumped-Parameter-Part Control

PART I Basic Deterministic Theory of LQ and Predictive Control

Lq-stochastic Control

Robust frequency-shaped LQ control

Certain frequency-shaped standard linear quadratic (LQ) controllers involving state feedback have attractive loop robustness properties. These robustness properties may vanish in passing to an output feedback scheme, as when state estimates are used instead of states. The known exception to date is when the plants are minimum phase and state estimation with loop recovery is used, as in LQG/LTR ...

Optimal Lq-feedback Control for a Class of First-order Hyperbolic Distributed Parameter Systems

The Linear-Quadratic (LQ) optimal control problem is studied for a class of first-order hyperbolic partial differential equation models by using a nonlinear infinite-dimensional (distributed parameter) Hilbert state-space description. First the dynamical properties of the linearized model around some equilibrium profile are studied. Next the LQ-feedback operator is computed by using the corresp...

A lumped parameter model of cerebral blood flow control combining cerebral autoregulation and neurovascular coupling.

Cerebral blood flow regulation is based on a variety of different mechanisms, of which the relative regulatory role remains largely unknown. The cerebral regulatory system expresses two regulatory properties: cerebral autoregulation and neurovascular coupling. Since partly the same mechanisms play a role in cerebral autoregulation and neurovascular coupling, this study aimed to develop a physio...
