    Simulation and Experimental Analysis of Servo Drive System Using Fuzzy PID Technology of Manipulator Consisting of Electric Steering Gear Based on Orthogonal Optimization by CHEN Rui, ZHOU Haibo, YU Hengbin, LI Xia

    Published 2020-04-01
    “…In order to improve the accuracy and stability of the motion control of the manipulator consisting of electric steering gear, a fuzzy PID intelligent control method based on orthogonal test method is proposed In this paper, the electric steering gear is used as the actuator, and the mathematical model of the pickup robot joint servo drive system is established The orthogonal experimental design and fuzzy control method are added under the traditional PID (proportion, integration, differentiation) control strategy In the Simulink software simulation environment, the openloop control, orthogonal optimization PID control and fuzzy PID control of the manipulator joint drive system are simulated, and the motion control experiments of singledegreeoffreedom and doubledegreeoffreedom manipulators are carried out Simulation and experimental analysis show that the PID parameters can be adjusted by orthogonal test method, which can quickly determine the appropriate PID parameters and greatly reduce the number of trials The fuzzy control can improve the adaptability of PID control, which can significantly reduce the overshoot of the system, slightly increase the rise time and the adjustment time of the system, and improve the accuracy and stability of the system…”

    Capacity Benefit Analysis of Pumped-storage Power Stations in a New-type Power System by ZHANG Xiangcheng, TIAN Xu, ZHANG Guihong, LIU Fei, FAN Hengjian, LI Zhiyi

    Published 2023-02-01
    “…The investment and construction of pumpedstorage power stations will bring multiple benefits to the safe and reliable operation of the new power system, and capacity benefits are the basic guarantee for maintaining the balance of power supply and demand.However, at this stage, the capacity benefits of pumped storage power plants are not fully recognized and compensated, resulting in unsatisfactory profitability and poor enthusiasm for investment and construction.To promote the development of pumpedstorage power plants in the process of energy to power transition, this paper proposes a capacity benefit evaluation method for pumped storage power stations based on the concept of production and operation simulation; a pumped storage power station is established.The joint optimization operation model of energy power station and wind, light, water, fire and other types of power sources is established. …”
