Cooling panel wall system with difference types of cooling mediums [PDF]

open access: yes, 2020
Global warming has caused worldwide average surface temperature to rise about 0.74oC during the past 100 years, which is partly aggravated by air-conditioning that releases chlorofluorocarbons (CFCs) and forming a vicious cycle.

Improving the Hardware Complexity by Exploiting the Reduced Dynamics-Based Fractional Order Systems

open access: yesIEEE Access, 2017
Fractional calculus is finding increased usage in the modeling and control of nonlinear systems with the enhanced robustness. However, from the implementation perspectives, the simultaneous modeling of the systems and the design of controllers with ...

Adaptive Second Order Recursive Terminal Sliding Mode Control for a Four-Wheel Independent Steer-by-Wire System

open access: yesIEEE Access, 2020
An adaptive second order recursive terminal sliding mode (SO-RTSM) is developed for the steering angle control of a four-wheel independent steer-by-wire (4WI-SbW) system.

Modified Nonlinear Integral Sliding Mode Control for Satellite Attitude Stabilization Using Magnetically Suspended Gimbaled Momentum Wheel [PDF]

open access: yes, 2015
This paper treats the attitude stabilization problem for satellite using only one MSGMW (Magnetically Suspended Gimbaled Momentum Wheel). To start, the coupled dynamic model of satellite and MSGMW is defined and simplified based on the fact that the ...

Minimum time control of the rocket attitude reorientation associated with orbit dynamics [PDF]

open access: yes, 2015
In this paper, we investigate the minimal time problem for the guidance of a rocket, whose motion is described by its attitude kinematics and dynamics but also by its orbit dynamics.

Governor design for hydropower plants by intelligent sliding mode variable structure control [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2016
This work proposes a neural-fuzzy sliding mode control scheme for a hydro-turbine speed governor system. Considering the assumption of elastic water hammer, a nonlinear mode of the hydro-turbine governor system is established. By linearizing this mode, a

Robust Simulation for Hybrid Systems: Chattering Path Avoidance [PDF]

open access: yes, 2015
The sliding mode approach is recognized as an efficient tool for treating the chattering behavior in hybrid systems. However, the amplitude of chattering, by its nature, is proportional to magnitude of discontinuous control.

Integral sliding mode control for active suspension systems of half-vehicle model

open access: yesMechanical Engineering Journal, 2015
This paper proposes a design method of sliding mode controller with the robustness against actuator uncertainty for active suspension systems of half-vehicle model. The features of the proposed sliding mode controller are not to require any force sensors
