Abstract

This paper proposes a feedback linearization control scheme for affine nonlinear systems with a constrained control signal where a fast response is required. Instead of placing the linearized system poles at exact locations, ray-like paths in the left hand plane are selected where the poles can freely vary to efficiently exploit the admissible input signal range to increase the speed of response. A stability test for the proposed method is derived via the multivariable circle criterion and the Kalman–Yakubovich–Popov lemma. Simulation results demonstrate how the method significantly increases the speed of response in spite of the input constraints compared to fixed pole placement.
