© 2003 IFAC. This work focuses on synthesizing nonlinear decoupling controllers for multi variable nonlinear systems represented by a state-space model, in the presence of deadtimes. Simple sufficient conditions for feasibility of closed-loop deadtimes are derived, which rely only on the structural properties of the system. A control law is then derived so that the closed-loop system is input/output linear and decoupled, with deadtimes equal to the smallest ones that satisfy the feasibility conditions. The performance of the proposed method is evaluated through simulation of a chemical process.
