in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

Robot automation increases productivity, the product quality and frees man from involuntary, unhealthy and dangerous work. While computational power has increased exponentially during the last decades, the limitations in flexibility constitute today a bottleneck in the further evolution of robotic systems. One application for intelligent systems is seam tracking in robotic welding. Seam trackin...

in this paper, control of a non-isothermal continuous stirred tank reactor in which two parallel autocatalytic reactions take place has been addressed. the reactor shows chaotic behavior for a certain set of reactor parameters. in order to control the product concentration, an optimal state feedback controller has been designed. since concentrations of reactor species are not measured, an obser...

radio frequency identification (rfid) is used to identify the characteristics of an object wirelessly using radio waves. the purpose of this technology in this study is mainly focused on healthcare for inventory management and theft control replacing the manual logs. the storage and tracking of high-cost inventory items is developed. automatic reordering and billing interfaces are designed for ...

Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...

In this paper, using the State Dependent Riccati Equation (SDRE) method, we propose a Robust Optimal Integral Sliding Mode Controller (ROISMC) to guarantee an optimal control law for a quadrotor which has become increasingly important by virtue of its high degrees of manoeuvres ability in presence of unknown time-varying external disturbances and actuator fault. The robustness of the controller...

to enhance the closed loop performance in presence of disturbance, uncertainties and delay a double loop mixture of mpc and robust controller is proposed. this double loop controller ensures smooth tracking for a 3-axis gyro-stabilized platform which has delay intrinsically. this control idea is suggested to eliminate high frequency disturbances and minimize steady state error with minimum powe...

This paper presents a solution to on-board trajectory tracking control of quadrotors. The proposed approach combines the standard hierarchical control paradigm that separates the control into low-level motor control, mid-level attitude dynamics control, and a high-level trajectory tracking with a model predictive control strategy. We use dynamic reduction of the attitude dynamics and dynamic ex...

Introducing relevant software technologies may provide significant advantages to a software organization. Unfortunately, the value the technology may provide is almost never quantified. We describe a methodology for precise quantitative measurement of the value a software technology may add to the project in terms of the impact on quality and lead time. The methodology employs measures derived ...
