The transport system as we know it today has not changed in the past 100 years except for the invention of aeroplanes. There has been a huge advancement in the individually transport classes but not in the system itself. As there are several problems with the present transport system, new ideas to a smarter transport system arises. One of these ideas is the General Transport System or GTS, which consist of magnetically levitating pods travelling along a guide rail controlled by intelligent computers. This project investigates how these pods can be levitated and how this is controlled. This is done by making a small- scale test setup where the concept zero-power control is utilised. This project utilize permanent magnets as a bias force and a coil as actuator which is controlled. A zero-power controller is used to minimise the current by controlling the levitated mass into the equilibrium position. Five different position controllers are designed and tested on the system. The test showed that a lag-lead controller was the best compared to a lead, lead-PI, PD and PID controller.
