This paper describes some of the theoretical and practical aspects of the design of a multi-variable control system needed to provide stable suspension of a vehicle. A number of sources of interaction between the variables of a magnetic suspension with several degrees of freedom have been discussed, in a first analysis the steady state interactions have been shown to depend on the relative positioning of transducers and magnets. Such interactions can be strongly influenced by introducing cross-coupling between measured and output variables in the controller. The nature of magnetically suspended vehicle is such that the dynamic interactions in the rigid body equations may be neglected and this leads to the possibility of reducing the multivariable controller design to a series of non- interacting single loop designs. Results from experimental apparatus and analog computer simulations have been found to be generally in agreement with the analytical principles.
