Hd. Tuan et S. Hosoe, ON ROBUST H-INFINITY CONTROL FOR NONLINEAR DISCRETE AND SAMPLED-DATA SYSTEMS, IEEE transactions on automatic control, 43(5), 1998, pp. 715-718
The linearization technique for H-infinity control for nonlinear discr
ete and sampled-data systems is developed in a unified Framework under
minimal assumptions. It is shown directly, without using any Riccati
or Hamilton-Jacobi-Isaacs equation, that H-infinity control for a line
arized system is also H-infinity control for a nonlinear original one.
