This paper presents a speed-sensorless control algorithm for induction motors, based on the stator fluxoriented control. The algorithm has the advantage of insensitivity to rotor parameters and load varying, stator flux and rotor speed is closed loop controlled respectively. The main improvement is that stator flux is estimated based on a modified integrator which is developed to solve the problems associated with pure integrator. The performance of the proposed algorithm is verified using a dSPACE system with DS1103 controller board based on the digital signal processor (DSP) TMS320F240. The experimental results show the estimated speed is true of exactly actual speed and good behavior of the drive in both transient and steady state lowspeed operating conditions is proved. ©2010 IEEE.

H∞ Static Output control of Discrete-Time Networked control systems with an Event-Triggered Scheme

Circuits, systems, and Signal Processing 2018年第2期37卷 553-568页

作者： Yan, Shen Zhang, Guangming Li, Tao Shen, Mouquan Li, Lingchun College of Electrical Engineering and Control Science Nanjing Technology University Nanjing211816 China School of Information and Control Nanjing University of Information Science and Technology NanjingJiangsu210044 China Key Laboratory of Measurement and Control of Complex Systems of Engineering Ministry of Education Southeast University Nanjing210096 China

This paper is devoted to the event-triggered H∞ static output feedback control of linear discrete-time networked control systems. With the help of zero-holder, a time-delay formulation is adopted to describe the even-triggered output. Resorting to Finsler lemma and time-delay techniques, a co-design framework of event-triggering communication and static output controller is established in terms of linear matrix inequalities. Meanwhile, the required H∞ performance could be ensured by the proposed framework. Two examples are supplied to verify the validity of the proposed method. © 2017, Springer Science+Business Media New York.

This paper aims to investigate an extended state observer (ESO) based control approach for the ground-coupled heat pump system (GCHP). As GCHP system has strong disturbances, a feasible approach of disturbance rejection should be proposed necessarily. ESO is employed to estimate the disturbance and compensate it to the controller to eliminate effects of the disturbance. By using ESO-based control and comparing with traditional control method, a better control performance is obtained through simulation verification. © 2015 IEEE.
