Optimal Control of Pendubot System Using SIMATIC S7-1200

Abstract

In optimal control, a common problem is developing a control law that can drive a dynamical system from one state to another as quickly as possible. The objective of paper is to design optimal control approach based SIMATIC S7-1200 for under-actuated Pendubot system. The main contribution of this paper is to introduce and validate control method for laboratory model of Pendubot system by using industrial device, namely, Programmable logic controller (PLC). Besides, Lyapunov Analysis is used to analyze the stability of optimal control. The simulation is performed in MATLAB/Simulink environment and experiment is carried out in TIA PORTAL environment. The simulation results and experimental results illustrate that the proposed control method is effective and robust by using PLC.
