In this paper, a multi-area Automatic Generation Control (AGC) scheme with Renewable Energy Sources (RES) suitable in a restructured interconnected power system has been proposed. Photo-voltaic and wind turbine generating system has been integrated with the grid. The developed scheme has been investigated for frequency control with and without RES units. A PID controller has been used to contro...

The dynamic interactions between a mobile manipulator and its vehicle are shown to lead to poor performance when conventional fixed-base controllers, which neglect these interactions, are used. An extended jacobian transpose control algorithm is developed, which accounts for dynamic vehicle motions caused by manipulator motions. It is shown to perform well, even in the presence of modeling erro...

We have already proposed a bilateral control scheme with energy balance monitoring under time-varying communication delay. In this paper, experimental results using the proposed control scheme over the computer network are shown. In the previous work, we dealt with a situation when the communication is in breakdown. However, we did not discuss how to recover the system after the communication l...

We adopt the robust control, or game theoretic, approach of [5] to option pricing. In this approach, uncertainty is described by a restricted set of possible price trajectories, without endowing this set with any probability measure. We seek a hedge against every possible price trajectory. In the absence of transaction costs, the continuous trading theory leads to a very simple differential gam...

Conventional fixed-base controllers are shown not to perform well on mobile manipulators due to the dynamic interactions between a manipulator and its vehicle. An extended jacobian transpose control algorithm is developed to improve the performance of such manipulator systems. It is shown to perform well in the presence of modelling errors and the practical limitations imposed by the sensory in...

In the present paper, we discuss a design method for a multirate system, in which the update interval of the control input is shorter than the sampling interval of the plant output. In this multirate system, the intersample output may oscillate between sampled outputs even if the sampled output converges to the reference input because the control input can be changed between sampled outputs. In...

The bluetongue (BT) epidemic that has prevailed in Europe since 2000 is the first example of continental spread of the BT virus (BTV) in large naive populations of susceptible animals. Based on the results of intensive surveillance and research in countries of the southern Mediterranean that were affected by the infection early on in the epidemic, a new strategy for prevention and control of th...

Progress in aircraft designs heavily depend on automatic flight control system. Modern aircraft have a wide flight envelope (linear and nonlinear) region. This study considers the design of stability and control augmentation system (SCAS) in high angle of attack region for a modern type aircraft via back stepping method. Because of highly nonlinear phenomena in aerodynamic parameters, a locally...

The intermittency of renewable energy sources, e.g. wind or solar, as well as forecast uncertainties in load, price and renewable infeed profiles call for storage solutions and appropriate control strategies. For the investigations in this paper the energy hub modeling framework is used, which takes into account multiple energy carriers, distributed generation, energy storage systems and renewa...

We present a new approach to handle dependencies within the general framework of case-control designs, illustrating our approach by a particular application from the field of genetic epidemiology. The method is derived for parent-offspring trios, which will later be relaxed to more general family structures. For applications in genetic epidemiology we consider tests on equality of allele freque...
