Feedback linearizing excitation control on a full-scale power system model

Infinite-Bus-Equivalent Estimation From Local Measurements on a Synchronous Machine

“…The first important result based on external feedback linearization (Marino, 1984), was further developed by several authors, for example Mak (1992), Mielczarski and Zajaczkowski (1994), King et al (1994), Jain et al (1994), Akhrif et al (1999), Jiang et al (2001). An alternative to this linearization technique is given by the direct feedback linearization, recent results being available for instance in (Guo et al, 2000;Guo et al, 2001).…”

Transient stability improvement through excitation control

“…Early nonlinear excitation controllers proposed were based on feedback linearization [14,6,9]. These were very important results to establish limits and possibilities for nonlinear control in power systems, but direct practical application of these design methods by themselves seems unlikely.…”

“…Then, the closed-loop system takes the form (9), (10) and (i) x * is the unique equilibrium such that…”

“…Feedback linearization was one of the early strategies to be explored for nonlinear excitation control design, with applications proposed to both single and multimachine systems, even with output feedback and state observers (see [9,6,14,19] among others). However, robustness issues against parameter uncertainties and unmodelled dynamics have not been solved, neither stability analysis in the output feedback case.…”

Integral Sliding Modes with Block Control of Multimachine Electric Power Systems

“…To analyze the EPS entire operation region, nonlinear control design techniques are more appropriate. Various nonlinear techniques have been implemented, e.g., control based on direct Lyapunov method (Machowsky et al, 1999), feedback linearization (FL) technique (Akhkrif, et al, 1999, Wu & Malik, 2006 including backstepping (Jung et al, 2005King et al, 1994, intelligent neural networks (Venayagamoorthy et al, 2003, Mohagheghi et al, 2007, fuzzy logic (Yousef & Mohamed, 2004) and normal form analysis (Kshatriya, et al, 2005, Liu et al, 2006.…”
