A pid control algorithm is used to study the dynamics of an electro-hydraulic: proportional speed control system (EHPSCS) with a single-rod hydraulic actuator, because the pid control algorithm is simple in operation, is characteristics of good computer real-time control, and possesses the good adaptability of changing parameters of control system and it is easily implemented in engineering applications. Experimental research on the speed control under the conditions of the different temperatures of hydraulic oil is carried out for an EHPSCS. Furthermore, the performance of the EHPSCS is analyzed through measuring the inlet pressure, the outlet pressure of the proportional valve and the pressure difference between the inlet pressure and the outlet pressure of the proportional valve. Experimental results show that the pid controller has good dynamics.

Aiming at the difficulty in control in tea fixation process, the intelligent control technology is adopted in the research which is for the core to the C8051F340 SCM and adopts the multi-point detection system to collect the temperature and humidity data. Besides, the data transmission with the epistemic machine can be realized by the (IC)-C-2 Bus, SPI and so on while the control rules and parameters of the controller can be intended. Thus it can be seen that the multi-parameter control of the temperature and humidity can be realized in tea green removing technology.

SOFT COMPUTING 2020年第1期24卷 17-40页

作者： Mendez, Gerardo M. Montes Dorantes, P. Noradino Aracelia Alcorta, M. Inst Tecnol Nuevo Leon Av Eloy Cavazos 2001 Guadalupe Nuevo Leon Mexico Univ Autonoma Noreste UANE Div Estudios Posgrad & Invest Blvd Jose Musa de Leo & Gen Medardo de la Pena Saltillo 25100 Coahuila Mexico Univ Autonoma Nuevo Leon Phys & Math Sch Ave Univ S-N San Nicolas De Los Garza 66455 Nuevo Leon Mexico

This work presents a new design to dynamically adapt the proportional, the integral and the derivative (pid) controllers gains using three interval type-1 non-singleton type-2 fuzzy logic systems (IT2 NSFLS-1), one fuzzy system for each gain of the pid, being the first main contribution of this proposal. This assembly is named as hybrid IT2 NSFLS-1 pid. Each IT2 NSFLS-1 system requires two non-singleton input values each period of discrete time (k), (1) the error e(k) and its standard deviation sigma e(k), and (2) the change of error Delta e(k) and its standard deviation sigma Delta e(k), to calculate the corresponding adjustment Delta KP(k), Delta KI(k), and Delta KD(k) for the pid controllers gains K-p(k), K-i(k), and K-d(k). The second main contribution of this proposal is that the parameters of each IT2 NSFLS-1 system are tuned each period of discrete time (k) by the non-singleton backpropagation (BP) algorithm using the plant output error and its standard deviation, which are processed as non-singleton values together with its non-singleton partial derivatives with respect to each IT2 fuzzy system parameter. Then these updated gains are used by the pid controller to calculate the best control signal for the plant under control. The uncertainty and the mean value of the measurement are used to calculate the non-singleton error which is processed as (a) input and (b) as gradient vector by each of the three IT2 NSFLS-1 systems. Simulation results show that the proposed hybrid assembly presents the better performance than the next five benchmarking control systems (a) the classic Zeigler-Nichols pid controller, and (b) four hybrid assemblies using pid controller and fuzzy systems with fixed fuzzy rule bases (T1 SFLS, T1 NSFLS, IT2 SFLS, IT2 NSFLS-1). The proposed assembly produces the better performance in a shortest period of time and it maintains a stable behavior on the output of the second-order plant model subject to variations and noise.

Due to the low effectiveness and poor quality of manual crimping of grounding wires, the author proposes the design of an automatic crimping device for connecting tube grounding wires based on intelligent fully automatic technology. The device consists of a microcontroller, an upper computer control interface, an electric push rod, an infrared sensor, a pressure transmitter, and other devices. The staff used the upper computer monitoring interface to set the relevant parameters for grounding wire crimping, and used X-ray digital imaging technology to measure the crimping size of the grounding wire. The size met the set parameter conditions. Through the pid control algorithm in the microcontroller, the stepper motor was controlled to push the clamp to move, completing the automatic crimping of the grounding wire. The X-ray detection method was introduced to detect the quality of the grounding wire after the crimping was completed. The experimental results show that the average deviation between the measured crimping size of the grounding wire and the actual measurement size by the automatic crimping device is only 0.06 mm, indicating that its measurement results are accurate;The success rate of crimping exceeds 95%. The above experimental results verify that the designed crimping device has high stability and reliability, and good quality detection effect.

In this study, we delved deeply into the intelligent control technology of electrical pressurization, utilizing a fuzzy neural network-based pid approach. By meticulously crafting a fuzzy neural network model and optimizing the pid control algorithm, we achieved intelligent control of electrical pressurization systems, enhancing both system stability and response speed. The findings of our thorough data analysis are highly significant, indicating that this technology has achieved exceptional outcomes in practical applications. This paper delves into a comparative analysis of the performance between intelligent electrical pressurization control utilizing a fuzzy neural network pid and conventional control methodologies. Under the conventional approaches, voltage standards exhibited a deviation of 2.5% along with a fluctuation span that reached as high as 5%. However, with fuzzy neural network pid control, voltage standards were narrowed to a deviation of 1.5%, with a fluctuation range reduced to 3%. Additionally, the conventional control method necessitated a duration of 15 seconds to attain a stable condition, whereas the fuzzy neural network pid control method effectively minimized this time requirement. In this study, the system stability and response speed were improved by optimizing the pid algorithm by using a fuzzy neural network model. Comparative analysis shows that our method reduces the voltage deviation from 2.5% to 1.5% and reduces the fluctuation range from 5% to 3%. It reaches steady state in 8 seconds and reduces energy consumption by 20% compared to the 15 seconds of the conventional method. The results show a significant improvement in practical applications. Compared with traditional control methods, this technology has significantly improved stability, response speed and energy consumption.

Vascular Interventional Surgery (VIS) is the common but conventional method to cure the vascular disease. Teleoperation, a promising surgery is used to protect the surgeon from X-ray radiation as well as to solve the problem of lacking experienced surgeons in remote rural areas. In this paper, a mathematical model of the damper has been built to get the relationship between the current of the coil and the damping force. According to the mathematical model, a pid control algorithm was designed to improve the accuracy of force feedback. The slave manipulator detect the force of catheter when being inserted into the blood vessels, then the master manipulator produce an equal damping force by a damper based on magnetorheological fluids. The comparison experiments between control mode with the pid algorithm and control mode without pid algorithm have been done to verify the performance. The result shows that the error with the pid control algorithm is small, which indicates the pid algorithm can improve accuracy of the force feedback.
