Abstract
As presented in previous chapters, DCALS may be linearised for an operating air-gap, and the linearised system can be stabilized using conventional classical controllers. In the previous chapter, two electromagnet-based magnetic levitation systems have been demonstrated to suspend one cylindrical rod in the air. To achieve stable suspension of the rod, linearised modeling of the system has been developed at different operating air-gaps, and accordingly, some conventional classical controllers (lead, lead-lag, PID, PI plus lead) have been implemented. Thus, an optimization scheme for the proposed DCALS has been developed so that the prototype may stably operate over a wide area maintaining good performance.
