This code implements an adaptive control system comprising a plant model, reference model, and adaptive controller. The plant and reference models are represented as linear state-space systems, while the adaptive controller employs a nonlinear IO system to adjust control parameters based on input signals and system states. The adaptive controller's internal dynamics are governed by differential equations, facilitating real-time adjustments to the control law coefficients.

Stellarator coils offer a steady-state and stable plasma confinement design as an alternative to  traditional toroidal-shaped tokamaks. The current-carrying coils exert a twisting magnetic field to control the plasma flow. The steady-state nature of stellarators makes them a desirable candidate for fusion power plants because they require less energy to maintain the plasma confinement. Predicting and analyzing complex stresses and coil deformations are integral in developing supportive steel jackets surrounding HTS coils.

A typical model of doubly-fed wind farm connected to the grid through series compensation is provided, which can be used to study subsynchronous oscillation(SSO). LC resonance may occur between the stator inductance and the capacitance in the 500kV line. At some frequencies, the equivalent resistance of the rotor is negative, and the proportional factor of the inner current loop of the rotor-side converter(RSC) will amplify the negative resistance, resulting in unstable subsynchronous control interaction(SSCI) in the system.

This dataset is related to the paper “Quantification of feature importance in automatic classification of power quality distortions” (IEEE International Conference on Harmonics and Quality of Power, March 2020). It includes the features extracted from synthetic signals with power quality distortions obtained from a public model (doi: 10.1109/ICHQP.2018.8378902).

Our research addresses time-dependent hysteresis effects in adhesive packaged MEMS pressure sensors.
Typically calibrated inside a certain temperature and pressure range, they provide precise pressure measurements, given
that certain setting times after temperature changes are maintained. Signal errors arise when temperature changes
induce time-dependent viscoelastic relaxation in the adhesive which cannot be compensated by calibration. High precision

This work presents the performance evaluation of incremental conductance maximum power point tracking (MPPT) algorithm for solar photovoltaic (PV) systems under rapidly changing irradiation condition. The simulation model, carried out in Matlab and Simulink, includes the PV solar panel, the dc/dc buck converter and the MPPT controller. This model provides a good evaluation of performance of MPPT control for PV systems.
