Discontinuous Controller for Power Systems: Sliding-Mode Block Control Approach

Abstract: Based on the complete model of the plant, a sliding-mode stabilizing controller for synchronous generators is designed. The block control approach is used in order to derive a nonlinear sliding surface, on which the mechanical dynamics are linearized. This combined approach enables us to compensate the inherent nonlinearities of the generator and to reject high-level external disturbances. A nonlinear observer is designed for estimation of the rotor fluxes and mechanical torque.

“…Sliding mode controllers combined with singular perturbation theory [69], [72], [71] and the block control approach [46], [7] has been proposed for a synchronous machine connected to the power grid. Other examples of sliding techniques can be found in multimachine systems [32] and in motor applications as well [59] [43].…”

“…Variable structure control (VSC) is a feedback control action widely employed for this kind of systems. VSC have been proposed for a variety of mechanical and electrical systems, also including power converters [29], power systems [30], and electrical drives [31]. The design of a VSC for a given system entails the choice of a switching control law with the aim of forcing system's state trajectory towards a properly designed sliding surface in the state space, described by .…”

“…Application of these controllers to full order plant would cause undesirable chattering, since unmodelled dynamics can be excited. In (Loukianov et al, 2004) it was designed a sliding mode controller to regulate the terminal voltage and power angle for a single machine infinite-bus system, based on the eighth order generator model (two equations for mechanical dynamics and six equations for electrical ones for thermo electrical power system). In this case, an information about the power angle reference, ref δ , is required.…”
