Abstract
The high-order sliding-mode approach offers a robust way to solve numerous output-regulation problems when the system relative degree is known. Still the difficult cases remain when the relative degree does not exist, is very high, or the mathematical model is not reliable. The notion of practical relative degree is proposed, which generalizes the standard relative-degree notion for the cases of uncertain systems lacking certain mathematical model. Practical output regulation is ensured. Computer simulation and practical results confirm the theoretical approach.
