construction method of the optimal state feedback law for finite dimensional nonlinear regulator problems. The method is applied to construct a feedback law for the reduced order control model of the NavierStokes equations, and then we apply our feedback law to the original control system. Our method

the ability to regulate over a range of parameter values. Keywords: nonlinear regulators, bifurcation, flight control. 1 Introduction In order to achieve higher levels of maneuverability and efficiency, future aircraft will operate close to or even beyond open loop stability boundaries. For example

. The existence of a constraint admissible member of this family can be checked by solving a single linear or quadratic programming problem. The solution of this optimization problem yields the corresponding controller. These results are then used to devise a robust time–optimal control scheme for regulation

The linear quadratic regulator problem for the second order evolution system with boundary controls is studied. Case that the input#to#state map is non#admissible is treated assuming that the system is exponentially stabilizable by the passive feedback. It is shown that the optimal control

the control engineer with the chal-lenge of regulating highly unstable, strongly shaped plasmas with precision and reliability. Therefore, whether to improve fusion performance or to protect the machine components, the problem of reconstructing the plasma boundary is criti-cal for both diagnostic and control

sociologists (Hunter, 1953; Mills, 1956; Domhoff, 2009) who assert that a group of interconnected social elites controls the decision-making power in society, designs policies that work in their favor, and consequently obtains a disproportionate amount of distributional advantages. Connecting through dense

is a constrained two-point boundary value problem. This paper shows how this constrained problem can be transformed into an un-constrained problem and how to easily solve the related unconstrained problem with Matlab. The method is illustrated on the performance optimization of a simple semi

that there is room for their design and offer epistemological and methodological clarifications for this purpose. To start with, I explore the idea of problem situations and relate them to the gap between the pace of social and ecological events and our individual and collective capacities to deal with them
