Clutter Suppression Interference (CSI) is a common radar signal processing method, which efficiently suppresses ground clutter interference in radar received echoes and can greatly improve the signal-to-noise ratio of airborne synthetic aperture radar ground motion target indication (SAR/GMTI). However, the implementation of the clutter suppression algorithm in engineering is difficult because of the large number of filtering power coefficients to be calculated in real time. Based on this research background, this paper models the ground clutter of airborne radar, analyzes the principles and performance of three clutter suppression algorithms, CSI, ACSI and median cancellation ACSI, and performs engineering implementation. From the engineering experimental results, it can be seen that all three algorithms can improve the airborne radar signal-to-noise ratio and thus improve the recognition capability of moving targets, among which the median pair cancellation ACSI algorithm has the lowest false alarm probability and the greatest performance improvement. © 2023 IEEE.

In the weak grids with complex resistive-inductive line impedance, the P-f and Q-U control are intertwined and highly coupled, which severely restricts the power delivery capability and dynamic support performance of VSG. To tackle this problem, an enhanced power decoupling control is proposed with two aspects: 1) Based on the analysis of power coupling mechanism under resistive-inductive line conditions, the intrinsic causes of dynamic power coupling and steady-state power delivery deviations are revealed;2) A modified virtual impedance power decoupling method is proposed to eliminate the coupling between power loops, which can satisfy the conditions for dynamic power decoupling and power delivery demand simultaneously. The proposed method can effectively improve dynamic and steady power responses of VSG. Simulation tests are carried out to validate the proposed method. © 2023 IEEE.

Traditional virtual synchronous control strategies lack the ability to perform Low Voltage Ride Through (LVRT) in the event of a fault in the distribution network. When the original power command value is high, the steady-state output current may exceed acceptable levels, and the reactive power response time may be sluggish, thereby failing to meet L VRT requirements. This paper suggests an improved L VRT control technology for VSGs using synchronous rotation coordinates. The approach suppresses instantaneous current through virtual impedance and controls output current in sequence. An improved current and power control loop is introduced, allowing the VSG to inject reactive power within a specified time and calculate active and reactive power command values for L VRT requirements. The strategy avoids the impact generated during control mode switching and meets the power grid's LVRT requirements. Simulation results validate the effectiveness of the proposed approach. © 2023 IEEE.

This paper introduces a method that utilizes nonlinear mixed integer programming (MINLP) to determine the best location and size of capacitors in radial distribution systems (rdS) to enhance the voltage profile, decrease active and reactive power losses, and reduce the cost of capacitor installation. The proposed method is divided into two parts: the first part identifies potential bus locations for the capacitors by calculating the modified loss sensitivity index (MLSI), and the second part employs MINLP to calculate the optimal size of capacitors to be placed in the candidate buses. The optimization problem is refined by incorporating constraints. The effectiveness of the proposed approach was evaluated by applying it to 10, 33, and 69 bus rdS and comparing the results to those of six other methods. The simulation results indicate that the proposed method outperforms the others in terms of loss minimization, capacitor costs, and voltage profile improvement. © 2023 IEEE.

This paper proposes a novel approach for reducing integral saturation of PID controllers in quadrotor UAVs. The method is combining the feedfoward control into PID controllers. Using feedforward decreases PID's output value, and reduces the integral item value at the same time. This method can greatly improve the control accuracy, decrease the error, and acts faster. It gives two simple methods which can determine PID parameters and feedforward function, and these methods are easy to use. © 2024 ACM.

Under the Maximum Power Point Tracking (MPPT) control of wind turbines, the generator output power is difficult to respond to the frequency fluctuations of the power grid, and there is no standby active power to support the frequency control of the power grid. Advanced Adiabatic Compressed Air Energy Storage (AACAES) has the advantages of large capacity, zero carbon emission and long life, so the dynamic simulation model of all working conditions of wind power and AACAES system is established. A cooperative control strategy of the wind turbine based on variable power point tracking and AACAES system participate in the system primary frequency regulation is proposed, which provides a new application idea for AACAES system in the power supply side with relatively weak grid support strength. Compared with the direct configuration of energy storage to participate in bilateral regulation control, the energy storage capacity is reduced and the frequency regulation ability of the system is improved. Finally, simulations and experiments show that the primary frequency regulation capability of the proposed control strategy is significantly improved compared with the primary frequency modulation control under different working conditions, which lays a theoretical foundation for the establishment of grid-friendly AACAES power station. © 2023 IEEE.

In order to reduce grid conversions, this study suggests a hybrid alternating current/direct current microgrid. Multidirectional hybrid grid converters connect AC and DC networks. Networks in DC and AC connect sources and loads. Networks in DC or AC can be used by energy storage devices. Use hybrid grids or connect them. Transmission of alternating and direct current electricity as well as reliable operation in the face of shifting demand and generation conditions are provided by coordination control systems. The efficiency of the control techniques used for the system's various components' ability to adapt to changing situations is examined. The system's capabilities are demonstrated by the simulation results produced in MATLAB/SIMULINK. Variations in solar irradiation were well managed, and a constant DC connection voltage of 500 V was maintained throughout. The hybrid microgrid continuously delivered 10 kW of electricity to DC loads to ensure uninterrupted operation. Battery activities were seen, and current dynamics and state of charge (SOC) lined up as anticipated. © 2023 IEEE.

Timely adjusting the brightness of indoor lighting equipment as the outdoor light intensity changes can not only improve the efficiency of equipment use and enhance user comfort, but also avoid causing energy waste. However, traditional lighting adjustment methods do not fully consider the impact of outdoor light intensity changes on indoor lighting, which leads to unsatisfactory lighting effects and a significant waste of resources. This paper proposes a method of indoor illumination adjustment based on fuzzy PID control algorithm, which can significantly solve the above problems. n the hardware part of the system, a high-performance Arduino microcontroller is used as the core controller. The indoor light intensity is detected in real time by the light sensor, and the brightness of the lighting equipment is adjusted by sending a PWM pulse width modulation signal through the microcontroller. Users can remotely control the turning on or off of lighting devices from the mobile phone client. The MATLAB/Simulink simulation of the lighting system shows that compared to traditional PID control, fuzzy PID control has significant improvements in response time and overshoot, which proves that using fuzzy PID controller to adjust indoor lighting brightness can achieve satisfactory results. © 2024 IEEE.

Developing a safe, stable, and efficient obstacle avoidance policy in crowded and narrow scenarios for multiple robots is challenging. Most existing studies either use centralized control or need communication with other robots. In this paper, we propose a novel logarithmic map-based deep reinforcement learning method for obstacle avoidance in complex and communication-free multi-robot scenarios. In particular, our method converts laser information into a logarithmic map. As a step toward improving training speed and generalization performance, our policies will be trained in two specially designed multi-robot scenarios. Compared to other methods, the logarithmic map can represent obstacles more accurately and improve the success rate of obstacle avoidance. We finally evaluate our approach under a variety of simulation and real-world scenarios. The results show that our method provides a more stable and effective navigation solution for robots in complex multi-robot scenarios and pedestrian scenarios.
