Modeling and Predictive Control of Hybrid System

چکیده
This paper deals with Mixed Logical Dynamical (MLD) approach. It allows to model the hybrid systems involved continuous, discrete dynamics and constraints. The changes or the switches which may appear over such dynamics are modelled by using the auxiliary variables take into account the interconnections. The applicability of this approach is illustrated by the modelling of the two tank system. The resultant system is well-posed for Model Predictive Control (MPC) that is used as control strategy for the system. The MPC needs to solve an optimization problem, including logic constraints. The translation of this problem into the Mixed Integer Quadratic Programming (MIQP) formulation is described also. Simulations were performed using the Hysdel compiler to illustrate the efficiently of this formalisme and prove the influence of increasing the prediction horizon. Keywords— Hybrid System, MLD, propositional logic rules, Mixed-Integer Programming, MPC.

Hybrid model predictive control of a nonlinear three-tank system based on the proposed compact form of piecewise affine model
In this paper, a predictive control based on the proposed hybrid model is designed to control the fluid height in a three-tank system with nonlinear dynamics whose operating mode depends on the instantaneous amount of system states. The use of nonlinear hybrid model in predictive control leads to a problem of mixed integer nonlinear programming (MINLP) which is very complex and time consuming t...

In present study, dynamic modeling and control of a tethered space robot system in trajectory tracking of its end effector is investigated. Considering variation of the tether length in the model, dynamics of the system is modeled using Lagrange’s method. Librational motion of the tether is controlled by adjusting the tether length similar to conventional manipulators,control of the robot...
