  • Implement of a Cascade Integral Sliding Mode Controller for a Water Tank Level Control System
    2008 3rd International Conference on Innovative Computing Information and Control, 2008
    Co-Authors: Hong-ming Chen, Zi-yi Chen
    Abstract:

    In this paper, a cascade integral sliding mode Control for a water tank Level Control System was proposed to realize Level position regulating and tracking Control. The key feature of this Control scheme is use of cascade back-step design method for the cascade nonlinear water tank Level System to improve the Control performances. The validity of the proposed Control scheme is verified through practical testing on an experimental tank Level System device. In the cases of step, multi step, and sinusoidal Level position command inputs, the test results show that the proposed Control scheme is capable of improving the tracking precision.

    Co-Authors: Hong-ming Chen, Zi-yi Chen, Juhng-perng Su
    Abstract:

    In this paper object, design a sliding mode Controller for a water tank liquid Level Control System to realize Level position regular and tracking Control. The key feature of this Control scheme is design a different zero of the sliding surface to raise adjusting degree of freedom and improve the Control performance. The validity of the proposed Control scheme is verified through practical testing on an experimental liquid Level Control device. In the cases of step, multi step, and sinusoidal command inputs, the test results show that the proposed Control scheme is capable of improving the tracking precision.

  • Development and Implementation of a High-Level Control System for the Underwater Remotely Operated Vehicle VISOR3
    IFAC-PapersOnLine, 2017
    Co-Authors: Alvaro De Jesús Gómez Gómez, Julio C. Correa, Luis M. Aristizabal, Carlos A. Zuluaga, Rafael E. Vásquez
    Abstract:

    Abstract This paper addresses the design and implementation of a high-Level Control System for the planning, supervision, and mission operation of the observation class remotely operated vehicle VISOR3. This work was developed following the Waterfall Model for the Software Development Life Cycle. First, a brief description of the ROV VISOR3 is made. Then, the functional and non-functional requirements, that are based on the ISO/IEC/IEEE 29148:2011 and were gathered from stakeholders, are presented. The software architecture is based on the standard ISO/IEC/IEEE 42010:2011. The implementation of the high-Level Control System is done by using a high-Level programming environment using layers through parallel executed threads. This architecture establishes a flexible structure and guidelines that orient the implementation of future components for the mission Control System of the ROV.

  • Development of a Low-Level Control System for the ROV Visor3
    International Journal of Navigation and Observation, 2016
    Co-Authors: Rafael E. Vásquez
    Abstract:

    This paper addresses the development of the simulation of the low-Level Control System for the underwater remotely operated vehicle Visor3. The 6-DOF mathematical model of Visor3 is presented using two coordinated Systems: Earth-fixed and body-fixed frames. The navigation, guidance, and Control (NGC) structure is divided into three layers: the high Level or the mission planner; the mid-Level or the path planner; and the low Level formed by the navigation and Control Systems. The nonlinear model-based observer is developed using the extended Kalman filter (EKF) which uses the linearization of the model to estimate the current state. The behavior of the observer is verified through simulations using Simulink®. An experiment was conducted with a trajectory that describes changes in the and and yaw components. To accomplish this task, two algorithms are compared: a multiloop PID and PID with gravity compensation. These Controllers and the nonlinear observer are tested using the 6-DOF mathematical model of Visor3. The Control and navigation Systems are a fundamental part of the low-Level Control System that will allow Visor3’s operators to take advantage of more advanced vehicle’s capabilities during inspection tasks of port facilities, hydroelectric dams, and oceanographic research.

  • Development and implementation of a low-Level Control System for the underwater remotely operated vehicle Visor3
    OCEANS 2016 MTS IEEE Monterey, 2016
    Co-Authors: Santiago A. Zuluaga, Carlos A. Zuluaga, Rafael E. Vásquez, Julio C. Correa
    Abstract:

    This paper addresses the development and implementation of a low Level Control System for the underwater vehicle Visor3, developed by the Universidad Pontificia Bolivariana, located at Medellín, Colombia. Visor3 is an observation class ROV that was developed for surveillance and inspection of port facilities and underwater structures and has been used as a test platform for the development of robotic technology for underwater exploration of Colombian seas. Both, the Control and navigation algorithms were implemented in the on-board processor (BeagleBone embedded computer). This processor is running an Ångström operating System which is a Linux distribution used in embedded devices with built-in components. The Control and navigation algorithms were tested in a hardware in the loop (HIL) environment using a 6-DOF mathematical model of Visor3 before the real test. Results from the HIL simulation and experimental test are compared. Results show that the HIL is powerful tool for the NGC development of the ROV.

  • performance assessment for the water Level Control System in steam generator of the nuclear power plant
    Annals of Nuclear Energy, 2012
    Co-Authors: Zhi Zhang, Lisheng Hu
    Abstract:

    Abstract The steam generator water Level Control System is the most important components of a nuclear power plant. The operating steam generator water Level Control System is increasingly recognized as a capital asset that should be routinely maintained and monitored. However, the Control loop performance assessment is still an open problem; thus, the performance assessment technology will be brought into the steam generator water Level Control System in nuclear power plants. Performance assessment methods for the plant with stable and unstable zeros of two PI Controller Systems are developed at all specific power Levels. The numerical examples will demonstrate the effectiveness of the proposed method.

    Abstract:

    Steam generator water Level Control System is the most important components of the nuclear power plant. The operating steam generator water Level Controller is increasingly recognized as a capital asset that should be maintained and monitored routinely. However, this issue as the Control loop performance assessment problem is still open. Considering this issue, a major contribution of this paper is to take the performance assessment technology into this industrial area, steam generator water Level Control System in nuclear power plants, where not much work has been done before. In terms of a class of steam generator water Level Control Systems, two PI Controller Systems, performance assessment methods for the plant with stable and unstable zeros are developed at specific power Level. An numerical example shows the effectiveness of the proposed method.
