Nonlinear Control Design for a Magnetic Levitation System
This thesis presents the design of two magnetically levitated high precision positioning systems based on permanent magnet linear synchronous motors (PMLSMs). Magnetic levitation based on PMLSMs requires the motors to operate with a variable airgap length but previous research in the field has studied mainly motors fastened by bearings; therefore, this work first models a motor with free normal...
متن کاملModeling and Control Design for a Magnetic Levitation System
We study the problem of controlling the position of a platen levitated using linear motors in threedimensional space. We develop a nonlinear six-state model of the system and provide two nonlinear controllers solving the set point stabilization problem. The first controller is derived by decomposing the model in two subsystems, applying feedback linearization to one of them, and using the invar...
متن کاملOptimization of Magnetic Levitation System
In magnetically levitated system in certain applications like magnetically levitated train or bearingless motors the distance between the magnet and the levitated object has to be constant. The nonlinear system in such cases can be linearized and transfer function of the system is obtained. But a proper controller is required to manipulate the current through the magnet coil. The simplest contr...
متن کاملOptimal Controller Design for Linear Magnetic Levitation Rail System
In many applications, magnetic suspension systems are required to operate over large variations in air gap. As a result, the nonlinearities inherent in most types of suspensions have a significant impact on performance. Specifically, it may be difficult to design a linear controller which gives satisfactory performance, stability, and disturbance rejection over a wide range of operating points....
متن کاملNonlinear Model & Controller Design for Magnetic Levitation System
This paper aims at development of non linear dynamic model for Magnetic Levitation System and proposed linear and nonlinear state space controllers. The linear controller was designed by linearizing the model around equilibrium point, while nonlinear controller was based on feedback linearization where a nonlinear state-space transformation is used to linearize the system exactly. Relative degr...
