in this article, the sliding mode control of frequency load control of power systems is studied. the study areaconsists of a system of water and heat. first, a mathematical model of the proposed system disturbances ismade and then sliding control mode for frequency load control is provided. by the system simulation andsliding mode control, it can be shown that the damping of oscillations is wel...

In recent years, incremental rate of electrical demands made many challenges for policy makers of power systems. Besides, due to economic crisis and environmental concerns about the air pollution, the new investments in thermal power generation units have experienced a noticeable reduction. For this reason, the power system operators should propose novel approaches to make a balance between inc...

Title of Thesis: Control of Construction Costs During Construction David H. Foo, Master of Science in Management Engineering, 1981 Thesis directed by: Dr. John M. Ciborski, Special Lecturer The construction of a major project requires a vast amount of time, money, material and human resources. Proper coordination of these elements into an array of activities is crutial to the success of the pro...

FALL 2015 61 There is a growing interest in electrical cars. Since 2012 there has been an increase of 170 percent in electrical cars worldwide (as of July 2014) (Trigg and Telleen 2013).1 Yet one of the most reported reasons for refraining from changing to electrical cars is the relatively limited travel range they have in comparison to gasoline-powered cars. Extending the travel range is of co...

The notion of input-to-state stability (ISS) is now recognized as a central concept in nonlinear systems analysis. It provides a nonlinear generalization of finite gains with respect to supremum norms and also of finite 2 gains. It plays a central role in recursive design, coprime factorizations, controllers for nonminimum phase systems, and many other areas. In this paper, a newer notion, that...

Producers might permit products to reach ultimate users by whatever routes happen to emerge and might be indifferent o the prices charged at various tages of the distributive process. However, the many disadvantages of such a strategy bring attempts to control both the distributive structure and the prices charged ultimate users. Different control mechanisms were chosen by oil companies in the ...
