Active magnetic bearings (AMBs) support a rotating shaft, inside a stator, contactless. Their major benefit in respect to hydrodynamic journal bearings is the possibility of operating in much higher rotational speeds (above 20.000 RPM). This is due to the fact that, their angular velocity is only limited by the strength of the shaft material and always they have stabilized operation without any mechanic contact. Also, AMBs are resulting in long life time, without the use of any lubrication system, eliminating thus the complexity of the lubricant network and promoting green operation of the rotating machines. Furthermore, the electromagnetic bearings are active elements that allow the measurement and the control of the position of the shaft, targeting in most accurate equilibrium positions, in terms of the shaft operation. Therefore, a suitable control system is required for a magnetic bearing, to exploit the above advantageous operational characteristics. In this study, the model of the control system of a Magnetic Bearing in terms of sensors and power amplifiers is presented and its design guidelines are explicitly described. As a first step, the non linear equation of the movement of the shaft inside the magnetic bearing, in one direction (y-axis), is introduced. Then, the linearization of this particular equation in a specific equilibrium point is performed and presented. Consequentially, the linear equation is transformed via Laplace method and the model of the Active Magnetic Bearing is finally developed. In addition to these, the sensor and the power amplifiers are modeled, to simulate the AMB system as a whole. The Matlab software is used to simulate the components that the AMB is consisted of. The P, I and D gains are the result of this simulations, which are produced via robust control method, in Single-Input-Single-Output (SISO) tool module of Matlab. At the end, the Simulink module of Matlab is energized to check the control characteristics of the develop

In this paper, a sliding mode controller with a generalized H 2 performance is proposed for a unicycle-like mobile robot to implement the trajectory tracking mission. First, a kinematic controller is introduced for the mobile robot and generating the desired values of the linear and angular velocity for the dynamic controller. Secondly, a dynamic controller based on the sliding mode control with a generalized H 2 performance is proposed to make the real velocity of the mobile robot and reach the desired velocity command. The stability properties of the controllers are proved by the Lyapunov method. This control law providing smaller errors and better performance to deal with the slipping of the wheels and parameter uncertainty. Simulation is carried out for a mobile robot to verify the performance of the proposed control scheme.
