The Permanent Magnet Synchronous Motor (PMSM) drive system is extensively utilized in high-precision positioning applications that demand superior dynamic performance across various operating conditions. Given the non-linear characteristics of the PMSM, a neuroadaptive sensorless controller based on B-spline neural networks is proposed to determine the control signals necessary for achieving the desired performance. The proposed control technique considers the system’s non-linearities and can be adapted to varying operating conditions, all while maintaining a low computational cost suitable for real-time operation. The introduced neuroadaptive controller is evaluated under conditions of uncertainty, and its performance is compared to that of a conventional PI controller optimized using the Whale Optimization Algorithm (WOA). The results demonstrate the viability of the proposed approach.

This paper presents a current-based control for a proton-exchange membrane fuel cell using the so-called double dual boost topology. In particular, we introduce a discrete time controller that, in coordination with a particular selection of inductors and capacitors, minimizes the switching ripple at the input port (current ripple) and the output port (voltage ripple) of the double dual boost converter. This converter has a particular characteristic, in contrast to the classical interleaved boost topology, in the double dual boost, the phases of the converter can have different duty ratios. The freedom to choose the duty ration for each phase can be used to select the operative point in which the input current is equal to zero. However, if individual controllers are used for each branch of the converter, the equilibrium after a transient can differ from the minimum ripple operation point; the proposed scheme regulates the output voltage and, at the same time, ensures the equilibrium remains in the minimum ripple operation in steady state. In this way, the converter can mitigate the harmonic distortion on the current extracted from the proton-exchange membrane fuel cell, which is beneficial to improve the efficiency and lifetime of the cell, and on the output voltage delivered to an output direct current bus. The results of the experiment are presented to validate the principles of the proposed system.

Improved interleaved Ćuk power converter

2023 , Robles-Campos, Héctor R. , Rosas-caro, Julio , Valderrabano-Gonzalez, Antonio , Posada, Johnny

An improved interleaved Ćuk power converter called in short –"Interleaved Two"– is designed and presented in this article. It is investigated and compared to a similar interleaved Ćuk power converter named as –"Interleaved One"– . The result is that the "Interleave Two" topology requires less reactive elements than the "Interleaved One" to achieve same performance, it will offer the possibility to reduce its size and economic cost. The operational principle and modeling is presented thoroughly. Moreover, simulation results comparing steady state time, output voltage, input current ripple and efficiency are presented. Additionally, in order to validate the performance of the "Interleaved Two" converter experimental results are included.
