- Abstract:
- Different types of motion mechanisms can be found in any complicated or simple mechanical structure and linear motion is one of the most frequently used mechanisms for sure. In recent years, a wide variety of designs are developed to create linear motion, each one having many positive and negative points. Among already existing designs, those based on linear actuation are more considerable compared to those using a mechanical convertor to transform rotary motion to linear motion. This thesis presents two newly designed linear motors which utilize linear electromagnet actuators in their structures. In this study nonlinear models are developed for two linear motors. Although all conditions and limitations existing in real situations are not covered here, but the model is accurate enough for developing the proper control policy. A nonlinear controller based on feedback linearization control law is developed considering both theoretical and experimental aspects. Finally, two electronic circuits are developed according to these control laws. The details of implementation of the two new linear motors including a comparison are included in the final chapters of this thesis.
