Observer design for Safe switching for the non linear system of the chemostat with Monod growth rate
Summary:
In this diploma thesis, the nonlinear model of the system of a chemostat with a Monod growth rate will be presented. The linear approximation of the system as a function of the equilibrium points of the system and the parameters of the nonlinear model will be presented. The simulation of the open loop system will be implemented. Next, the relationship between the system parameters and the identification coefficients of the linear model will be presented. The linear model of the system as a function of the equilibrium points of the system and the coefficients of identification will be presented. The open loop linear system simulation will be implemented. A full-order state observer based on the linear model of the system with the coefficients of identification will be presented. The simulation of the open loop system and the observer will be implemented. A stepwise safe switching algorithm between the equilibrium points of the system will be designed. The simulation of the open-loop system will be implemented to transition to various equilibrium points of the nonlinear system.
