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.

Electronically controlled air suspension (ECAS) system has been extensively applied in vehicles to increase driving comfort, fuel economy, and operation safety. However, due to the nonlinear and hysteresis characteristics of the ECAS system, accurately controlling suspension height remains challenging. To tackle this problem, a bench test is conducted on the air spring and solenoid valve to establish their mathematical model for their characteristics. Based on this, a mathematical model of the ECAS system is developed by integrating suspension kinematics and dynamics theories. Then, a height control strategy is devised utilizing a fuzzy proportional-integral-derivative (pid) algorithm, enabling precise control of the vehicle's body height. Based on this, an adaptive weight particle swarm optimization (AWPSO) algorithm is utilized to optimize the output range of the fuzzy controller. The effectiveness of the proposed model and control strategy is validated through both simulation tests and real-vehicle testing under both no-load and full-load conditions. These tests confirm the proposed approach's effectiveness in achieving precise suspension height control in ECAS systems.

This paper investigates the force servo hydraulic press control system based on fuzzy pid algorithm. Since the force servo pressure of the hydraulic control system which manifests the manufacture quality is affected by the external load acting on the hydraulic cylinder, the mathematical model of the force servo hydraulic press system (FSHPS) based on the feed-forward compensation correction is established. The steady state error reduction and the phase lead correction of the system are carried out. The open-loop time domain and frequency domain indicators of the FSHPS illustrate the stability of the system, but the control performance such as rapidity and accuracy need to be improved. According to the transfer function of the FSHPS, a fuzzy pid control scheme is designed. The simulations of the system show that the control performance of the FSHPS based on the fuzzy pid algorithm is greatly improved.

Drilling and sampling are the most direct and effective methods available to study Antarctic subglacial lakes. Based on the Philberth probe, a Recoverable Autonomous Sonde (RECAS) allows for in situ lake water measurement and sampling, through the addition of an upper thermal tip and a cable recoiling mechanism. RECAS-200, a prototype of RECAS, has a drilling depth of 200 m, a surface supply voltage of 800 VAC and a downhole power of similar to 9.6 kW during drilling. In this study, a heating control system for RECAS-200 was designed. The system avoids the need for high-power step-down converters, by separating heating power from control power, thereby reducing the overall weight of the probe and avoiding the need to increase cable diameter. We also introduce a self-developed, small, solid-state, 800 VAC power regulator and a fuzzy pid temperature control algorithm. Their purpose was to manage the power adjustment of each heating element and to provide closed-loop temperature control of certain heating elements which can easily burn out due to overheating. Test results indicated that the proposed RECAS-200 heating control system met all our design specifications and could be easily assembled into the RECAS-200 probe.
