A novel cascaded vector control scheme for the Modular Multilevel Matrix Converter

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011
This paper presents a novel cascaded vector control scheme for the Modular Multilevel Matrix Converter (M3C). The inner current control loops allow an independent control of the input and output converter currents. The outer energy control consists of average, vertical and horizontal balancing control loops to equalize the energy stored in the nine ...

Motion and Morphology Planning for Autonomous Manipulation in Clutter With a Shape‐Shifting, Variable‐Stiffness Robot

Advanced Intelligent Systems, EarlyView.
A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Energy‐Aware Perturbation Optimization for Memristor‐Array Convolutional Neural Networks

Advanced Intelligent Systems, EarlyView.
Memristor‐array inference becomes more energy efficient when layer inputs are reshaped before computation. Sinusoidal perturbation encoding with dual‐threshold screening reduces active voltage pulses and contracts ADC input‐current ranges, jointly lowering crossbar and peripheral energy while preserving accuracy across hardware MNIST validation, deep ...

Single‐Step Analog In‐Memory Matrix Computation in Three‐Dimensional Circuits

Advanced Intelligent Systems, EarlyView.
A wooden model illustrates a 3D memristive array designed for single‐step kernel convolutions. It shows how two‐dimensional input data are mapped into the 3D array and convolved in parallel with stored kernels. Color‐coded connection points represent programmed memory‐element values, with each color corresponding to a specific kernel weight.

Operating Performance of the Modular Multilevel Matrix Converter in Drive Applications

, 2015
The Modular Multilevel Matrix Converter (M3C) is an emerging topology, especially suitable for high torque low speed drive applications in the medium voltage range. One special benefit is the overload capability of the output currents. Up to 200% of the nominal values can be reached near standstill to overcome breakaway torques without additional ...
