We propose balancing related numerically reliable methods to compute minimal realizations of linear periodic systems with time-varying dimensions. The rst method belongs to the family of square-root methods with guaranteed enhanced computational accuracy and can be used to compute balanced minimal order realizations. An alternative balancing-free square-root method has the advantage of a potentially better numerical accuracy in case of poorly scaled original systems. The key numerical… CONTINUE READING
