Comparative Studies of Three MPPT Strategies for Solar PV System
Abstract: The solar power technology is one of the most predominant technologies that serve as a major source of power supply. But, its initial cost is too high and its lesser efficiency has not made its use very attractive as an alternate. Hence, it is quite critical to use maximum power available from the solar PV panel and operate it at its highest energy conversion output. For this, the solar PV …

Design of Decentralised PI Controller Based on Characteristic Ratio Assignment Method for a Waste Water Treatment Plant
Abstract: This work proposes a decentralised PI controller design for a wastewater treatment plant (WWTP) based on the Characteristic Ratio Assignment (CRA) method. To minimise interactions, a decoupler is created, and for every decoupled subsystem, the First Order Plus Dead Time (FOPDT) model is derived. Using the CRA technique, the independent controllers for each lower order FOPDT decoupling subsystem are calculated. This paper presents the design of a decentralized proportional–integral (PI) …

Performance Analysis of Induction Motor using DTC Technique
Abstract: AbstractDirect Torque Control is a control method used for high-performance torque control in AC drive systems. The standard DTC drive includes a couple of hysteresis comparators, a flux and torque estimator and a selection table for voltage vectors. Torque and flux are governed simultaneously by implementing appropriate voltage vectors, and de-coupling control of torque and flux can be accomplished by restricting these amounts within their hysteresis bands. The DTC requires …
