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.

The motion control of underwater spherical robot is a complicated process, which has the characteristics of high inertia and non-linearity. There are many influencing factors for the underwater spherical robot motion such as ambient temperature and water current, so it is difficult to obtain the real-time kinematic model. Therefore, it is hard for traditional pid to achieve stable motion control of the underwater spherical robot. In this paper, the actual motion control of underwater spherical robot was realized that used fuzzy pid control method. Compared with traditional pid for the underwater spherical robot, fuzzy pid has some advantages, such as good robustness and good dynamic performance. To demonstrate that the fuzzy pid was more suitable to our underwater spherical robot, we carried out some real time experiments. Comparison experimental results demonstrated that the fuzzy pid control method has better dynamic performance than the traditional pid.

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.

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.
