Output derivatives are used to form control.
Further, implementation of the controller requires measurement of output derivatives.

This paper presents the design of continuous-time controller based on the higher order output derivatives in the feedback loop.
It is known that these types of observers use the output and the output derivatives of the observed system as its inputs.
If the observability mapping is injective in the whole, the system can be transformed into a normal form, from which the estimation of the successive output derivatives can be easily carried out.
