2009 article

Lyapunov Redesign of Adaptive Controllers for Polynomial Nonlinear Systems

2009 AMERICAN CONTROL CONFERENCE, VOLS 1-9, pp. 5144–5149.

By: Q. Zheng n & F. Wu n

author keywords: Adaptive control; parametric uncertainties; higher-order Lyapunov function; SOS programming
TL;DR: This paper will develop an adaptive control scheme in attenuating the effect of the unknown parameters on the controlled output, which is composed of tracking errors and control efforts, and formulate the synthesis conditions of adaptive control as polynomial matrix inequalities.

2009 journal article

Regional stabilisation of polynomial non-linear systems using rational Lyapunov functions

INTERNATIONAL JOURNAL OF CONTROL, 82(9), 1605–1615.

By: Q. Zheng n & F. Wu n

author keywords: polynomial non-linear systems; rational Lyapunov function; domain of attraction; regional stabilisation; SOS programming
TL;DR: A new non-linear stabilisation approach based on the popular linear parameter-varying control techniques is proposed that is extended to a class of output-dependent non- linear systems where the stabilising output-feedback controller can be synthesised using rational Lyapunov functions of outputs.

2008 journal article

Output feedback control of saturated discrete-time linear systems using parameter-dependent Lyapunov functions

SYSTEMS & CONTROL LETTERS, 57(11), 896–903.

By: Q. Zheng n & F. Wu n

author keywords: actuator saturation; parameter-dependent Lyapunov function; output feedback control; domain of attraction; restricted l(2) gain
TL;DR: The proposed output feedback control law asymptotically stabilizes the open loop system with a larger domain of attraction and achieves better disturbance attenuation under energy and magnitude bounded disturbances. (via Semantic Scholar)

2007 journal article

Output feedback stabilization of linear systems with actuator saturation

IEEE TRANSACTIONS ON AUTOMATIC CONTROL, 52(1), 122–128.

By: F. Wu n, Z. Lin* & Q. Zheng n

author keywords: actuator saturation; domain of attraction; invariant set; output feedback; stability
TL;DR: The note presents a method for designing an output feedback law that stabilizes a linear system subject to actuator saturation with a large domain of attraction that applies to general linear systems including strictly unstable ones. (via Semantic Scholar)
