Automation, with its mathematical sub-domain Control Theory, studies the properties and control of dynamic systems in engineering. Each controlled system is made up of commands (we also say input or control) u, states x, and outputs y. The goal of control theory is to design control so that states and outputs achieve a defined goal. The controls act on states which usually represent the internal dynamics of the system. While the outputs representing measurable components are related to states. When the control depends only on the output measurement and only the error between the reference and the measured output is used in the design, the control is called feedback (also known as feedback). Feedback control or the one-degree-of-freedom framework often fails for nonlinear systems, where there is no asymptotically stable global solution that satisfies the constraints of the systems. To deal with system disturbances, in this thesis, we use Modeless Control. The Command without Model (CSM), presented by Michel Fliess and Ceric Join, has already proven its power through a wide range of successful applications, and even, with experimental results where the model of the system and its perturbations are unknown. Successful attempts for nonlinear modeless control and for modeless control for delay systems are presented respectively.
