This paper compares the control performance of a distributed control system with variable sampling to actuation delay when using two different control solutions. The first one is a pole-placement controller with a fuzzy delay compensator and the second one an adaptive pole-placement with fractional dead-time modelling. The delay compensator is added to an existing controller that does not take ...

Due to the continuous increment of the load demand, identification of weaker buses, improvement of voltage profile and power losses in the context of the voltage stability problems has become one of the major concerns for the larger, complex, interconnected power systems. If the voltage profile of the weaker buses is improved, the voltage stability can be improved significantly. Because of the ...

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...

With an increasing number of vehicles on the road, multiple-vehicle platoons have become a new solution under communication constraints. However, existing studies seldom consider effect tail vehicle information transfer and platoon control over long distances, thus performance time-varying delays is unacceptable. In this study, hierarchical multi-platoon architecture considering backbone sub-pl...

Recently the compensator has been shown to be an in expensive and reliable dose delivery device for photon beam intensity-modulated radiation therapy (IMRT). The goal of IMRT compensator design is to produce an optimized primary fluence profile at the patient's surface obtained from the optimization procedure. In this paper some of the problems associated with IMRT compensator design, specifica...

This paper deals with a design problem of a parallel feedforward compensator (PFC) which realizes the output feedback exponential passive (OFEP) system. One can easily design an adaptive output feedback control system for such nonlinear systems satisfying the OFEP conditions. We propose a design scheme of a PFC for making a non-OFEP nonlinear system OFEP. The nonlinear system considered here is...
