With the development of computer technology, the concept of computer automatic control has gradually penetrated the research field of aircraft power control, and intelligent power control systems have become mainstream research. The present work aims to improve the performance of the broadband phase-locked loop (PLL) based on the linear Kalman filter. Specifically, this paper first introduces linear Kalman filter and second-order generalized integrator (SOGI). Then, SOGI is added to PLL based on the linear Kalman filter. The purpose is to use the infinite gain effect of SOGI at the central angular frequency to eliminate the time-varying angular frequency component in the error when the system inputs SOGI to achieve a better filtering effect. Then, the system’s stability analysis and parameter settings are carried out to establish an intelligent phase-locked method of aviation variable frequency power supply. Finally, simulation experiments are performed. The experimental results demonstrate that PLL via the linear Kalman filter with SOGI can solve the problem that the output phase angle contains high-frequency components when the power supply voltage distortion rate is 10%. This scheme has a strong anti-interference ability under power grid voltage imbalance. The accuracy of the Long and Short-term Memory network used here is about 80%, which can well realize the intelligent aviation power frequency conversion control method. The research reported here provides a reference for establishing smart phase-locked technology of aviation variable frequency power supply.

In this paper, a simple extended Kalman Filter (EKF) controller for direct torque control (DTC) of a six-phase induction machine in all speed ranges is proposed. The aim of this paper is to decrease the execution time of EKF modeling of a six-phase induction motor. The proposed method is fast and can operate online. If the machine parameters are changed during the operation, the EKF algorithm is activated to find parameters used for controlling the motor. In low speed, not only the motor speed measurement but also the DTC of machine is difficult. The EKF model can estimate speed, flux, load torque, and stator resistance in low speed; thus, optimization can be performed in all loads and speed range. The proposed method increases the accuracy of DTC of the six-phase induction machine and decreases the computation cost of the system using the simplified algorithm. The simulation and experimental results verify the effectiveness and the robustness of the proposed method against parameter variations.

Renewable energy system (RES) based microgrid applications have grown extensively over the recent years. Owing to power fluctuations in RES, acquiring stable and accurate output voltage at the DC Bus is a major concern in DC microgrid applications. Presently, switching, as well as, prediction of output voltage for RES is quite slow and total harmonic distortion cannot be reduced to a minimal level. Accordingly, this research developed a controller for Multiple Input Single Output (MISO) DC to DC converter and a Kalman filter. Initially, four seriesconnected PV panels were modelled and analysed. A boost converter was used to combine PV panels' output and provide a single output at the DC Bus. Perturb and Observe, a Maximum Power Point Tracking (MPPT) algorithm, was used to retrieve optimal power from modelled RES. Analysis revealed that the output voltage waveform contained harmonics and had a Total Harmonic Distortion (THD) of 27.73 %. Thus, a Kalman filter was modeled and analysed to remove the harmonics. The THD value was consequently reduced to 2.1 %, which is quite within the allowable limit prescribed by IEEE, for the THD of a PV system. Analysis revealed that a stable and accurate output from a PV based RES could be achieved with the proposed scheme, and further THD was also well within limits prescribed by IEEE.
