ASSESSING THE EFFECTS OF TIME-DEPENDENT RESTRICTIONS AND CONTROL ACTIONS TO FLATTEN THE CURVE OF COVID-19 IN KAZAKHSTAN

Do, Ton Duc; Gui, Meei Mei; Ng, Kok Yew (PeerJ, 2021-02)

This article presents the assessment of time-dependent national-level restrictions and control actions and their effects in fighting the COVID-19 pandemic. By analysing the transmission dynamics during the first wave of ...
COYOTE OPTIMIZATION ALGORITHM FOR PARAMETERS ESTIMATION OF VARIOUS MODELS OF SOLAR CELLS AND PV MODULES

Diab, Ahmed A. Zaki; Sultan, Hamdy M.; Do, Ton Duc; Kamel, Omar Makram; Mossa, Mahmoud A. (Institute of Electrical and Electronics Engineers, 2020-06-08)

Recently, building an accurate mathematical model with the help of the experimentally measured data of solar cells and Photovoltaic (PV) modules, as a tool for simulation and performance evaluation of the PV systems, has ...
DEADBEAT-BASED MODEL PREDICTIVE VOLTAGE CONTROL FOR A SENSORLESS FIVE-PHASE INDUCTION MOTOR DRIVE

Mossa, Mahmoud A.; Vu Quynh, Nguyen; Echeikh, Hamdi; Do, Ton Duc (Hindawi, 2020-07-15)

This paper introduces a direct model predictive voltage control (DMP VC) for a sensorless five-phase induction motor drive. The operation of the proposed sensorless DMP VC is based on the direct control of the applied ...
Development of a Power Assist Lifting Device With a Fuzzy PID Speed Regulator

Raziyev, Yesset; Garifulin, Ramil; Shintemirov, Almas; Do, Ton Duc (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)

This paper introduces the development of a one-degree-of-freedom (1DOF) power assist device that helps to lift objects and facilitate the operator's job. The existing designs were examined for different control approaches ...
Direct-torque control system design using maximum torque per ampere method for interior permanent magnet synchronous motors

Do, Ton Duc; Nurtay, Bekarys; Duisenbay, Bota (Nazarbayev University School of Science and Technology, 2018-06-26)

The paper proposes a method for controlling interior Permanent Magnet Synchronous Motor (IPMSM) drives, that combines Direct-Torque control (DTC) and Maximum Torque Per Ampere (MTPA) in a synchronously rotating (d-q) frame. ...
PI anti-windup speed control of permanent magnet synchronous motor based on feedforward compensation

Do, Ton Duc; Zhetpissov, Yernar; Kaibaldiyev, Azamat (Nazarbayev University School of Science and Technology, 2018-06-26)

This paper designs simulation model of PI anti-windup speed controller based on a simple set-point weighting for the interior permanent-magnet synchronous motor (IPMSM). Firstly, a mathematical model of IPMSM drive system ...
POLYNOMIAL OBSERVER-BASED CONTROLLER SYNTHESIS AND FAULT-TOLERANT CONTROL FOR TRACKING OPTIMAL POWER OF WIND ENERGY CONVERSION SYSTEMS

Vu, Van-Phong; Ngo, Van-Thuyen; Do, Van-Dung; Truong, Dinh-Nhon; Quynh, Nguyen Vu; Bui, Phuc Duc-Hong; Mai, Vu The; Do, Ton Duc (Institute of Electrical and Electronics Engineers, 2020-08-13)

This article proposes a new approach to design a fault-tolerant control (FTC) scheme for tracking the optimal power of wind energy conversion systems (WECSs). In this article, the considered fault will not only impact ...
ROBUST MPPT OBSERVER-BASED CONTROL SYSTEM FOR WIND ENERGY CONVERSION SYSTEM WITH UNCERTAINTIES AND DISTURBANCE

Vu, Van-Phong; Ngo, Van-Thuyen; Do, Van-Dung; Truong, Dinh-Nhon; Huynh, Tuan-Tu; Do, Ton Duc (IEEE, 2021-07-05)

The problem of tracking the maximum power point for the wind energy conversion system (WECS) is taken into consideration in this paper. The WECS in this article is simultaneously affected by the uncertainties and the ...
ROBUST POSITION CONTROL OF AN OVER-ACTUATED UNDERWATER VEHICLE UNDER MODEL UNCERTAINTIES AND OCEAN CURRENT EFFECTS USING DYNAMIC SLIDING MODE SURFACE AND OPTIMAL ALLOCATION CONTROL

Vu, Mai The; Le, Tat-Hien; Thanh, Ha Le Nhu Ngoc; Huynh, Tuan-Tu; Van, Mien; Hoang, Quoc-Dong; Do, Ton Duc (Sensors, 2021-01-22)

Underwater vehicles (UVs) are subjected to various environmental disturbances due to ocean currents, propulsion systems, and un-modeled disturbances. In practice, it is very challenging to design a control system to maintain ...
