An Improved IPMSM Discrete-Time Nonlinear Model for Hardware-in-the-Loop Test Systems
Published on 2025-02-19 by Yingpeng Fan, Guoqing Zhu, Jian Luo @MDPI
Abstract: Interior permanent magnet synchronous motors (IPMSMs) exhibit significant nonlinear electromagnetic behaviour due to the effects of saturation, cross-coupling, spatial harmonics, temperature, and iron losses. In order to effectively capture the actual electromagnetic behaviour of IPMSMs, this paper proposes an improved IPMSM nonlinear model. The proposed model is based on the nonlinear flux-linkage model and progressively incorporates the effects of spatial harmonics, temperature, and iron losse[...]

Torque Ripple Minimization for Switched Reluctance Motor Drives Based on Harris Hawks–Radial Basis Function Approximation
Published on 2025-02-19 by Jackson Oloo, Szamel Laszlo @MDPI
Abstract: Switched reluctance motor drives are becoming attractive for electric vehicle propulsion systems due to their simple and cheap construction. However, their operation is degraded by torque ripples due to the salient nature of the stator and rotor poles. There are several methods of mitigating torque ripples in switched reluctance motors (SRMs). Apart from changing the geometrical design of the motor, the less costly technique involves the development of an adaptive switching strategy. By selectin[...]
Our summary: Minimization of torque ripples in switched reluctance motor drives using Harris Hawks optimization and radial basis function approximation for optimal switching angles. Fuzzy logic switching angle compensation strategy implemented for validation in numerical simulations.

Field Programmable Gate Array (FPGA) Implementation of a Multi-Symbol Detection Algorithm with Reduced Matching Branches and Multiplexed Finite Impulse Response (FIR) Filters
Published on 2025-02-19 by Kai Hong, Ruifeng Duan, Ling Zhao, You Zhou @MDPI
Abstract: The computational complexity of existing multi-symbol detection (MSD) algorithms grows exponentially as the observation intervals increase, resulting in difficulties in algorithm implementation for detecting pulse code modulation/frequency modulation (PCM/FM) signals, especially for multi-channel signals. To address the challenges, we proposed a low-complexity MSD algorithm based on the averaged matched filtering. The proposed algorithm groups the local reference signals based on the different i[...]
Our summary: Exponential growth in computational complexity of existing MSD algorithms for PCM/FM signals, proposed low-complexity algorithm based on averaged matched filtering, significant decrease in matching branches, optimization of FIR filters for hardware resource consumption reduction.

Neuron circuit
Patent published on the 2025-02-19 in EP under Ref EP4510043 by GUDE MICHAEL [DE] (Gude Michael [de])
Abstract: Convolutional neural networks (CNN) or spiking neural networks (SNN) are usually applied for implementation. Although CNNs can be realized purely digitally, they require a lot of energy due to the high processing power (MAC structures). SNNs can usually only be implemented with analog components and are therefore difficult to implement in circuits with a technology node below 10 nm.The present disclosure is aimed to realize electronic neurons that process pulse-width modulated signals. These neu[...]

Dynamics Research of the Hopfield Neural Network Based on Hyperbolic Tangent Memristor with Absolute Value
Published on 2025-02-17 by Huiyan Gao, Hongmei Xu @MDPI
Abstract: Neurons in the brain are interconnected through synapses. Local active memristors can both simulate the synaptic behavior of neurons and the action potentials of neurons. Currently, the hyperbolic tangent function-type memristors used for coupling neural networks do not belong to local active memristors. To take advantage of local active memristors and consider the multi-equilibrium point problem, a cosine function is introduced into the state equation, resulting in the design of an absolute val[...]
