Induction motors (IM) attracted many researchers in the last few decades. In this field, various applications are implemented, such as servo motor drives and electric vehicles. This work applies a sensorless direct torque controller (DTC) to control three-phase IM. System dynamics of IM were derived. A nonlinear dynamic model had introduced with white noise. Given complexity dynamics, Jacobean ...

This article is devoted to the fuzzy fault-tolerant tracking control of Markov jump systems with unknown mismatched faults. To reconstruct faults and system states, a sequence proportional–integral observers are established via outputs. With help structure separation technique, gains observer solved by unified linear matrix inequality framework. Resorting rebuilt states from an iterative estima...

This paper describes the stepper motor position control implemented using a novel nonsingleton type-1 fuzzy logic system to update the gains of the professional proportional-integral-derivative controller running on ATMEGA 2560 microcontroller. In this work, three controllers are compared: a) the professional proportional-integral-derivative controller, b) the type-1 singleton fuzzy logic syste...

In this paper, tuning of power system stabilizer (PSS) and thyristor controlled series capacitor (TCSC) is studied. The analysis of mode controllability is used to select the effective location for TCSC. The performances of TCSC equipped with a proportional-integral-derivative controller (P-I-D controller) and proportional-integral-derivative power system stabilizer (P-I-D PSS) are investigated...

evidence-based medicine (ebm) is becoming an integral component of graduate medical education competency and a requirement for grad medical education practice-based learning core competency. this study tries to compare the efficacy of conferences utilizing small-group discussions with the traditional conference method in enhancing ebm competency. the participants in this randomized controlled t...

Abstract Frequency control of an interconnected power system in the presence wind integration is complex since speed/power variations also affect frequency addition to load perturbations. Therefore, improving existing schemes necessary maintain a stable such scenarios. In this paper, new 2-degree freedom combined proportional-integral and derivative scheme applied integrated system. designing c...

This article presents an important finding: the parameters of secondary frequency control based on integral or proportional integral control can be tuned to achieve economic operation and frequency regulation simultaneously. We show that if the power imbalance is represented by frequency deviation, an iterative dual ascent based economic dispatch solving is equivalent to integral control. An it...
