Abstract: In this paper, the concept of a global generalised characteristic number is defined and global zero dynamics algorithm is developed. Based on the feasibility of this algorithm, a global diffeomorphism is constructed, under which the original system can be put into a global canonical form. Sufficient conditions for the existence of the global diffeomorphism are provided.
Keywords: nonlinear control; singular systems; global zero dynamics; differential-algebraic equations; canonical form; global diffeomorphism.
