Constant feedback coefficients of nearly optimal PID control of the magnetic suspension system for the linear driving mechanism were derived, and its robust stability against the scanning movement of the driven part was verified. The root loci have shown that the stability region of the system is narrowed by only 15% by neglecting the crossterms of the feedback coefficients. The stability analysis using the root locus method showed that the time delay inherent to the magnetic actuators, which was neglected when the optimal control rule was derived, has a substantial effect on the system stability. However, an allowable time delay in the control loop can be estimated to guarantee the system stability, even with scanning motion of rather long stroke.
