An input signal used in process identification - chaos sequence

The sequences which consist of any segment of a chaos sequence are called as C-sequences. These sequences could be used as a kind of input signals to replace M-sequences in the process identification. This substitution is theoretically proved to be feasible. Inverse C-sequences are created in a way similar to inverse M-sequences to solve the problem that C-sequences have nonideal balance property, that is, the numbers of ‘0’ and ‘1’ are unequal. Besides its good pseudo-random property, the sequences have other advantages such as easy to generate, varieties of the segment and adjustable cycle time.
