Dual Mode Control of an Inverted Pendulum: Design, Analysis and Experimental Evaluation

by Laura Álvarez-Hidalgo and Ian S. Howard

Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 6, Page # 120–143, 2023; DOI: 10.25046/aj080613

Abstract:

We present an inverted pendulum design using readily available V-slot rail components and 3D printing to construct custom parts. To enable the examination of different pendulum characteristics, we constructed three pendulum poles of different lengths. We implemented a brake mechanism to modify sliding friction resistance and built a paddle that can be attached to the…

Design and Implementation of Closed-loop PI Control Strategies in Real-time MATLAB Simulation Environment for Nonlinear and Linear ARMAX Models of HVAC Centrifugal Chiller Control Systems

by Nicolae Tudoroiu, Mohammed Zaheeruddin, Songchun Li and Elena-Roxana Tudoroiu

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 2, Page # 283–308, 2018; DOI: 10.25046/aj030233

Abstract:

The objective of this paper is to investigate three different approaches of modeling, design and discrete-time implementation of PI closed-loop control strategies in SIMULINK simulation environment, applied to a centrifugal chiller system. Centrifugal chillers are widely used in large building HVAC systems. The system consists of an evaporator, a condenser, a centrifugal compressor and an…
