Phosphate (Pi) deficiency limits plant growth and development, resulting in adaptive stress responses. Among the molecular determinants of Pi stress responses, transcription factors play a critical role in regulating adaptive mechanisms. WRKY75 is one of several transcription factors induced during Pi deprivation. In this study, we evaluated the role of the WRKY75 transcription factor in regula...

This paper focuses on the control of permanent magnet synchronous motors (PMSMs) utilizing a non-linear adaptive PI-Backstepping design and model harmonics reduction approach that uses an active shunt filter followed by cascade bandpass filter. While conventional backstepping may assure system's stability, it is often imprecise. It creates significant amount static error, which has detrimental ...

In power systems, the constant frequency, voltage, and output are desired determine quality of generated electrical energy. Therefore, frequency control is crucial in systems. The parameters conventional controllers used generation plants determined according to system's characteristics at stage installation, they cannot adapt changing system dynamics as lifespan increases. Thus, studies on aut...

It is known that constant power load (CPL) may cause a negative impedance, which seriously affects the stability of system. In this paper, new control algorithm for DC–DC buck converter feeding unknown CPL proposed. First, under assumption extracted load, standard passivity–based (PBC) presented to reshape system energy and compensate impedance proportion-integration (PI) action around passive ...

This paper deals with the application of artificial neural network (ANN) and fuzzy based Adaptive Neuro Fuzzy Inference System(ANFIS) approach to Load Frequency Control (LFC) of multi unequal area hydro-thermal interconnected power system. The proposed ANFIS controller combines the advantages of fuzzy controller as well as quick response and adaptability nature of ANN. Area-1 and area-2 consist...

This paper presents two methods for designing special purpose controllers for permanent magnet synchronous motor. The main target of the designed controllers is to reduce torque ripples of this type of motors. The first proposed adaptive method is based on two loop controllers (current controller and speed controller) in addition to using space vector pulse width modulation to maximize fundamen...

A novel architecture for integrating neural networks with industrial controllers is proposed, for use in predictive control of complex process systems. In the proposed method, a conventional controller, e.g., a proportional-integral (PI) controller, is used to control the process. In addition, a recurrent neural network is used in the form of a multistep-ahead predictor (MSP) to model the proce...

This paper presents an auxiliary passive circuit and control design for wireless power transfer (WPT) systems in DC microgrids to achieve optimal efficiency while maintain accurate output voltage regulation. An inductance is added at the transmitter resonator form a current sink ensure zero switching (ZVS) of primary-side full-bridge inverter with even extremely light load conditions. Moreover,...
