Online Adaptation of Data‐Driven Controllers for Unknown Nonlinear Systems

International Journal of Robust and Nonlinear Control, Volume 36, Issue 3, Page 1086-1095, February 2026.
ABSTRACT This paper considers data‐driven online control of input‐affine nonlinear systems. By resorting to a data‐based closed‐loop time‐varying system representation, we derive data‐based online semi‐definite programs that are computed along the system's trajectory.

Nonlinear Controller Design and its Optimization for Real‐Time Implementation for a Servo Motor Drive

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes an EXP‐PI controller as a practical alternative to the conventional PI controller, integrating EXP functions on the error and its rate within the control structure. The controller is optimized using five recent intelligent algorithms, with SFS providing the most effective parameter tuning.
