We give a new sufficient condition for the arbitrary pole assignability of a system by decentralized dynamic compensators. Using such condition we are able to derive a new bound on the degrees of decentralized dynamic compensators so that the generic systems have the arbitrary pole assignability.

t In this paper the most general Hz control problem is considered. We derive necessary and sufficient conditions when the infimum is attained by state feedback. We do the same for the measurement feedback case where we derive necessary and sufficient conditions when the infimum is attained by proper dynamic compensators. We also investigate reduced-order compensators if some states are observab...

Heave compensator is a system that mitigates transmission of heave movement from vessels to the equipment in the vessel. In drilling industry, a heave compensator enables drilling in offshore environments. Heave compensator attenuates movement transmitted from the vessel to the drill string and drill bit ensuring security and efficiency of the offshore drilling process. Common types of heave co...

Introduction: Radiotherapy is one of the effective methods in the treatment of cancer. In the recent methods of radiotherapy, intensity modulated radiotherapy (IMRT) technique by compensators is used. when photon beam passes the compensator, scattered photons can be generated within the compensator. The presence of scattered photons may complicate the design of compensators as...

Absmd-Often in controi system design. i t is only necessary to estimate a single (but prespecified) linear function of the system's state for the purpose of implementing a feedback control law. This can be achieved by a linear functional observer which may have order one less than the observability index of the plant. but generically cannot have smaller order. In this paper, we explore the conc...

The paper is concerned with defining and parametrising the families of all degenerate compensators (feedback, squaring down etc) in a variety of linear control problems. Such compensators indicate the boundaries of the control design, but they also provide the means for linearising the nonlinear nature of the Determinantal Assignment Problems, which provide the unifying description for all freq...

The output feedback pole placement problem of linear systems with static or dynamic compensators belongs to the classical problems in control theory and many theoretical and numerical research papers were already devoted to this problem. Although the considered systems are linear, the problem requires the solution of an over determined system of quadratic polynomial equations. A lot of progress...

The optimal coordinated tuning of a group of Static Var Compensators (SVC), in steady state, allows the Power Electric Systems (PES) to operate close to their overload limits, maintaining the voltage stability in several operating conditions. The mentioned tuning problem was considered as a Multiobjective Optimization Problem (MOP) with three objectives to optimize: the financial investment for...
