Nonlinear field voltage control of a synchronous generator using feedback linearization

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.…”

“…This control structure will be referred to as the dynamic extension of the controller (14). Since we are considering a single input system, in the present case the matrix A in the dynamic extension control reduces to a scalar, which we shall denote β.…”

“…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.…”

Adaptive Control for Power System Stability Improvement

“…The stabilization of the synchronous generator has represented an attractive problem for testing different concepts of the modern control theory. The majority of the contributions have presented the application of adaptive control, robust control (Chow et al, 1990), variable structure control (Subbarao & Iyer, 1993), fuzzy control (Hassan & Malik, 1993), artificial neural network (Zhang et al, 1993), feedback linearization (Mielcszarski & Zajaczkowski, 1994), and internal model control (Law et al, 1994). The presented research has been focused to the study of adaptive stabilization methods.…”

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).…”
