This paper addresses the design of a fuzzy control system with a fuzzy controller and a fuzzy estimator for a fossil fuelled drum boiler-turbine-generator unit on the basis of a dynamic fuzzy model that was developed in our recently published paper. In the design procedure, a dynamics augmentation is introduced and a dynamic fuzzy augmented system is then determined for the nonlinear boiler-tur...

Type-2 fuzzy logic systems have extensively been applied to various engineering problems, e.g. identification, prediction, control, pattern recognition, etc. in the past two decades, and the results were promising especially in the presence of significant uncertainties in the system. In the design of type-2 fuzzy logic systems, the early applications were realized in a way that both the anteced...

The Cassini-Huygens mission to Saturn is the end of an era for NASA; sending one large spacecraft equipped to carry out a multitude of scientific experiments. Future NASA missions will deploy many smaller spacecrafts in highly controlled spatial configurations in what is referred to as “formation flying.” Among the many challenges to this approach are: maintaining precise relative-positions, at...

Preservation of comfort conditions for buildings’ occupants and minimization of energy consumption and cost are the main targets of the energy and indoor environment management systems. This paper aims to achieve those targets by presenting the optimal operation of chilling systems within the building supervisory control systems using fuzzy control instead of a conventional Programmable Logic C...

Abstract This paper presents a low-cost method for real-time energy management in residences. Light, motion, temperature, and sound sensors are system inputs. Lighting, heating, cooling output powers set according to sensor data consumer conditions. The is controlled by using three different fuzzy logic inference engines together with microcontroller, sensors, Nextion HMI display. lighting, coo...

this paper presents a fuzzy search controller approach along with the look-up tables, to optimize the efficiency of a pump-induction motor drive. the induction motor and the converter are modeled based on thermal loss; and for modeling the pump and the hydraulic system, which are non-linear and relatively complicated, the neural network is used. in the designed system, in order to optimize the ...
