In the form of knowledge economy,high-tech enterprises with knowledge-based human resources become one of the backbone forces to promote the development of China’s knowledge economy.Due to the high mobility of high-tech talent,uncertainty of staff transfer and internal promotion,and the time delay of recruitment or dismissal,the knowledge worker system is a complex dynamic system.Research on the stability analysis and control methods of knowledge worker systems in high-tech enterprises is a research topic of great practical significance.This dissertation mainly studies the design of uncertain system modeling and control methods for knowledge worker systems with recruitment or dismissal delays.The details are as follows:Firstly,the system modeling of knowledge workers in high-tech enterprises with recruitment delays and its state feedback stabilization control problem is concerned.First of all,considering various types of employee transfers,recruitment behaviors and their time delays of recruitment,we establish an uncertain time-delay dynamics model for knowledge workers in enterprises.Then,based on Lyapunov-Krasovskii stability theory,the time-delay dependent conditions for the asymptotic stability on the closed-loop system of corporate employees are obtained,and the state feedback controller of the system is designed.Finally,the simulation results show that the designed state feedback controller can ensure the asymptotic stability of the time-delay system for knowledge workers.Secondly,the time-delay dynamics system of knowledge workers via sliding mode control is studied.First of all,consider the allocation of the ratio of direct onboarding and onboarding after an internship when the enterprise recruits or dismisses workers.Furthermore,consider the system of knowledge workers as a class of nonlinear systems and a time-delay dynamic model of knowledge workers is established.Then,study of dynamic stability of time-delay systems for knowledge workers using sliding mode control method.The final simulation results show that the design of sliding mode control method can stabilize the knowledge workers time-delay system asymptotically in finite time with good robustness and dynamic quality. |
