As the power system develops and the size of the grid expands, the composite electric field of transmission lines has an increasingly important impact on the safety and stability of the power grid. Traditional electric field prediction methods have certain shortcomings in accuracy and real-time performance, so more efficient and accurate prediction methods are needed to meet the needs of the power system. The synthetic electric field prediction method for transmission lines based on the fuzzy pid (Proportional-Integral-Derivative) algorithm has emerged to improve the reliability and stability of power grid operation. This article studies a method for predicting the composite electric field of transmission lines based on the fuzzy pid algorithm. By comprehensively considering fuzzy control and pid regulation, accurate prediction of the composite electric field of transmission lines can be achieved, improving the stability and reliability of power grid operation. The experimental data shows that the relative error of synthetic electric field prediction fluctuates between 2.5% and 15.67%, and the accuracy of fuzzy pid algorithm prediction is good.

In this study, we propose an optimized fuzzy proportional-integral-differential (fuzzy pid) algorithm used in a rapid temperature control system for automotive batteries. Based on the proposed algorithm, an intelligent thermal management system with temperature feedback mechanism is built by switchable thermoelectric (TE) devices in working mode, simultaneously offering both heating and cooling capabilities. Assisted by liquid cooling optimization, the battery pack temperature is rapidly converged by the regulation of TE devices. Experimental results demonstrate that the temperature of a thermal runaway battery pack can be lowered from 63.5 degrees C to 25 degrees C in just 280 s, while the temperature of a frozen battery pack can be raised from-10 degrees C to 25 degrees C within 185 s. Compared to multi-channel liquid cooling method, our temperature control time is reduced by approximately 76%. The innovative structure and optimized temperature control algorithm can obviously enhance the efficiency of the battery temperature control system in new energy electric vehicle field.

The Uninterruptible Power Supply (UPS) is a kind of power supply with electric energy storage, but most UPS systems bring harmonic pollution to the grid, and the power factor is inaccurate in the boost circuit, the output voltage is unstable. Therefore, an active power factor correction circuit (APFC) based on the current and voltage double closed-loop structure is designed in the boost circuit;besides, the fuzzy pid control algorithm is also proposed in the inverter circuit. The effectiveness of the proposed method can be verified by the computer simulation and real experiments, and there are four main results as follows. Firstly, the actual power factor of the UPS system can reach more than 0.996 with APFC correction circuit;then, the UPS system has the strong robustness and the shorter response time;in addition, the voltage regulation rate of the system remains at 0.083% and the load regulation rate is around 0.056%. Finally, the designed UPS system can provide the stable 36V +/- 0.2V (50 +/- 0.2Hz) AC power.

High-power LED is one of the important lighting sources of machine vision in industrial on-line detection system. However, the image quality of the detected object collected by the image sensor will change with the illumination intensity of lighting sources. It is necessary to ensure the stability of the detection ambient illumination so as to improve detection efficiency and quality. For this purpose, an adaptive dimming system of High-power LED based on fuzzy pid algorithm for machine vision lighting is designed to maintain constant detection ambient illumination. The proposed system is consisted of hardware design and software design. The hardware which uses DSP as the core control device includes constant current drive circuit for High-power LED, temperature of LED measurement circuit, and ambient illumination intensity of detection circuit. If the detection ambient illumination is not equal to the given ambient illumination, the fuzzy pid algorithm is started to adjust automatically the pid parameter according to the error and error rate in DSP chip. The duty cycle of PWM pulse generated by DSP is regulated with fuzzy pid algorithm. The experimental result shows that the adaptive constant of the measured ambient illumination can be achieved. The application of this system has certain reference value for energy-saving lighting and automatic dimming control of industrial on-line detection.

In order to improve in-wheel-motored electric vehicle(EV) yaw stability, the yaw stability control system based on fuzzy pid controller is carried out in this paper. Firstly, we set up the original models for controller: a 2DOF EV dynamics model and wheels with in-wheel motors model. Secondly, a control system which includes three parts: reference model, upper yaw stability fuzzy pid controller and lower moment distribution controller is designed. Besides, under the help of lookup table, the problem that fuzzy toolbox can't be downloaded into dSPACE is solved. Finally, we run the off-line and real-time simulation on a 8 degrees of freedom(DOF) in-wheel-motored EV model with unitire tire model to verify the effectiveness of the fuzzy MD algorithm.

Mode switching between engine and motor has an important impact on power and driving performances of hybrid electric vehicles. In this paper, the clutch fuzzy control strategy is investigated for the process of pure electric mode switching to engine single driving mode of a single-axis parallel hybrid power system equipped with automatic mechanical transmission (AMT) as an example. Based on the dynamics of mode switching process, three fuzzy controllers are designed: a fuzzy controller of driving intentions, a fuzzy controller of clutch target engagement speed, and a fuzzy pid controller of the actuator voltage of clutch. Simulation results show that the proposed control strategy can effectively reflect the driving intentions, and make the clutch engagement fast and smooth to ensure the smoothness and efficiency of the switching process from pure electric mode to engine single driving.
