“…Because the control bandwidth of the current loop in the system is much larger than the modal frequency of the double-flexible system, the influence of the current loop can be ignored and regarded as constant 1. In reference [26], the system transfer function was reduced by Pade method, and Equation (31) can be obtained as follows.…”

A high performance manipulator servo drive system is a double flexible system with flexible joints and flexible loads. Flexible joints are composed of elastic connecting elements, and flexible loads are flexible Euler beams with elastic deformation. The dual flexible system has highly nonlinear time-varying characteristics. This kind of characteristic will cause resonance of the double-flexible system and affect the dynamic characteristics of the system. In order to suppress the system resonance, the nonlinear dynamics model of the system with two flexible bodies is established. Then, the servo control method of double flexible body system is designed, and the range of PI controller parameters is determined by the same resistance pole assignment method. Then, a fuzzy control rule is designed to dynamically adjust PI controller parameters based on pole assignment. Finally, the improved fuzzy PI control strategy is simulated numerically. The simulation results show that the vibration of the double-flexible system can be effectively suppressed by establishing the precise dynamic model and designing PI controller parameters.

Efficient flowrate control is paramount for the seamless operation and reliability of petroleum transportation systems, where precise control of fluid movement ensures not only operational efficiency but also safety and cost-effectiveness. The main aim of this paper is to develop a highly effective modified model reference PID controller, tailored to ensure optimal flowrate control of petroleum products throughout their transportation. Initially, the petrol transportation process is analyzed to establish a suitable mathematical model based on vital factors like pipeline diameter, length, and pump attributes. However, using a basic first-order time delay model for petrol transportation systems is limiting due to inaccuracies, variable delay issues, safety oversights, and real-time control complexities. To improve this, the delay portion is approximated as a third-order transfer function to better reflect complex physical conditions. Subsequently, the PID controller is synthesized by modifying its structure to address flowrate control issues. These modifications primarily focus on the controller’s derivative component, involving the addition of a first-order filter and alterations to its structure. To optimize the proposed controller, the genetic, black hole, and zebra optimization techniques are employed, aiming to minimize an integral time absolute error cost function and ensure that the outlet flow of the controlled system closely follows the response of an appropriate reference model. They are chosen for their proficiency in complex optimization to enhance the controller's effectiveness by optimizing parameters within constraints, adapting to system dynamics, and ensuring optimal conditions. Through simulations, it is demonstrated that the proposed controller significantly enhances the stability and efficiency of the control system, while maintaining practical control signals. Moreover, the proposed modifications and intelligent tuning of the PID controller yield remarkable improvements compared to previous related work, resulting in a 36% reduction in rise time, a 63% reduction in settling time, an 80% reduction in overshoot, and a 98% reduction in cost value.

“…ere is much data information in the in-school cultivation data series or in the companies' ability requirement data series. e recognition of the relationship between the in-school cultivation and the companies' requirement needs to study some advanced intelligent analytics, such as the feature extraction techniques [22], data conversion methods [23], and convolution approaches [24]. Periconceptionally, an adaptive neural network is functional to establish models to resolve the feature relationship between different data series [25,26].…”

Optimal human resources allocation asks to employ a person to work in the position corresponding to his/her ability. Employment competence is the key feedback to the cultivation of college students’ working ability. The data relationship needs to analyze between the in-school cultivation items and the working abilities required by the companies. Machine learning framework is introduced to study the companies’ responses to the cultivation of college students. In this work, a dual-network architecture is built up for statistical modeling evaluation of college graduates’ working ability in consistence with their job position and remuneration. A requirement network and a cultivation network are constructed for extracting features from the original working ability data required by companies and cultivated ever in school. The networks are fully trained by adaptively tuning the linking weights. The extracted features are fused together to estimate the working competence of each target sample/person. To evaluate the dual-network model, a modeling index system is designed, including proposing a total evaluation index calculus for the dual-network model, and a variable importance index from the original data. The samples are consequently ranked by the model predicted index and by the variable importance index, respectively. The ranking difference is used to evaluate the prediction efficiency of the dual-network model. Experimental results show that the dual network architecture is feasible to establish statistical models for the evaluation of college graduates’ in-school cultivated working ability in consistence with the company’s required working ability at their job position and their deserved remuneration.
