Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.

Model Predictive Control (MPC) refers to a class of algorithms that optimize the future behavior of the plant subject to operational constraints. The merits of the class algorithms include its ability to handle imposed hard constraints on the system and perform on-line optimization. This thesis investigates design and implementation of continuous time model predictive control using Laguerre polynomials and extends the design approaches proposed in to include intermittent predictive control, as well as to include the case of the nonlinear predictive control.

The dissertation has five chapters and a list of references. The chapters concentrate on the following issues: In Chapter 1, we recall some classical results of the problem and some basic concepts from variational analysis and nonsmooth analysis. In Chapter 2, we investigate some new models of nonlinear nonlocal regularity; Chapter 3 is devoted to the study of metric perturbation of Milyutin-type regularity on a fixed set under composition of a set-valued mapping and a Lipschitz single-valued mapping;...
