| Abstract: | This paper is concerned with the problem as to whether a multi-input nonlinear system is equivalent to the so-called low-triangular form.Two elemental forms of multi-input lower-triangular systems are proposed. Then,using the theory of singular distributions,the necessary and suffcient conditions under which multi-input nonlinear systems are locally feedback equivalent to these two lower-triangular systems are established.Furthermore,algorithms are provided to describe how to realize these equivalent transf... |
