This study presents a sensorless static model based with output current estimation method for digital PWM control dc-dc converters. The static model is a feedforward type control method adopted in coordination with the standard PID control and it can improve characteristics of wide input and output range of dc-dc converter by using information of output current. The one of the drawbacks of the static...
We have proposed the sensorless model control based on the static model equation of the dc-dc converter that is able to change the bias value corresponding to changes of the load current, the input voltage and output voltage. The sensorless model control can regulate the output voltage. On the other hand, the transient response of output voltage is not improved. Therefore, an improvement of the transient...
Modeling of photovoltaic (PV) module remains as an important issue for many applications like monitoring or fault detection. Hence, many models have been proposed in literature, the most popular ones are the single and double diode models. Each model have unknown parameters to be identified. In this paper, a parameters extraction for both single and double diode models by using flower pollination...
Recently, the energy saving is required. It is necessary for the energy saving to operate the electric device in the sleep mode. Therefore, the output voltage rises abnormally because the dc-dc converter is required the operation in the discontinuous current mode. Therefore, we have proposed the model control using static model and strived for improvements. In the proposed method, the output voltage...
The purpose of this paper is to propose the digital control method that is comprised of the fast P control and model control for an improvement of the transient response of the dc-dc converter. The electronic devices are required the operation in the standby mode and the quick return to the active mode. The fast transient response of the dc-dc converter in such condition is important. In this paper,...
The purpose of this paper is to discuss a current prediction algorithm for sensorless model control dc-dc converter. In the proposed method, the sensing resistor for the current detection is eliminated by predicting the output current. The output current is predicted from the equation of the relationship between the output and input voltage in the static state using the duty ratio and the output voltage...

In this study a wound rotor AC induction machine which can be used in wind turbine is modeled in LabVIEW program and the system model optimization is done with system identification (SI) method. Wind turbines are usually used as synchronous and asynchronous. In this study, to be safe and because of the advantages such as low costs, WRIM is preferred. In the control of the excitation circuit, SI method...
Brushless DC motor has been used in many different areas intensively. In recent years, minimized sized Brushless DC motors which can produce large torques and achieve high velocities are produced. So that designers can develop robotic systems in insufficient place applications. Design engineers make modeling and simulation studies in computer environment to choose appropriate BLDC motor during developing...
Renewable energy sources are being progressively more used for providing energy needs due to the growing concern of environmental pollution. Photovoltaic (PV) systems have a significant place within the renewable energy sources. Solar cells are the most important elements of photovoltaic systems. They determine the parameters to meet the power requested. For this reason, a simulation program is necessary...
