Abstract The estimation method based on the electrochemical impedance spectrum can comprehensively describe reaction process of Li-ion battery without causing damage to battery, and is suitable for estimating state health battery. In this paper, equivalent circuit model established by analyzing ac internal corresponding each component composite link with curve segments in spectrum, parameters a...

Tracking the cell temperature is critical for battery safety and durability. It not feasible to equip every with a sensor in large systems such as those electric vehicles. Apart from this, sensors are usually mounted on surface do detect core temperature, which can mean detecting an offset due gradient. Many sensorless methods require great computational effort solving partial differential equa...

The tetrapolar electrode configuration used in bioimpedance suffers from negative sensitivity and is confounded by anisotropic tissue such as blood vessels or muscle and nerve fibres. We propose a circular array of electrodes to focus current directly underneath the probe and provide anisotropy information. We show that an implementation using 16 miniature electrodes is able to outperform the t...

A multiestimation-based adaptive controller is designed for robotic manipulators. Multiestimation based techniques can improve the transient response of adaptive systems by switching between the various estimation schemes. The switching process is subject to a minimum dwell or residence time in order to guarantee stability. Then, the multiestimation scheme is applied to the teleoperation of rob...

An increasing intake of grid-connected inverters could change the characteristics low voltage networks including equivalent grid impedance seen by each inverter at its point common coupling. This can impact overall performance inverters, and thus it becomes necessary for to estimate online. However, there are some challenges when comes estimation using inverters. These include accuracy associat...
