Klyuyev O. Multichannel system of discontinuous vector control asynchronous gates the cascade (synthesis and research)

The dissertation is devoted to the solution of a scientific - practical task of increase of control and power characteristics asynchronous gates of cascades (AGC). For regulation in AGC the speeds and reactive power are offered in one system to be realized principles of optimum and extreme control. The construction of relay vector system of the subordinated control AGC is carried out. Then the contour of extreme regulation with the given criterion functions and algorithm of operation of an extremal controller is added. Тhe interconnected multichannel control system as a two-level structure is de-veloped. The bottom level represents primary contours of stabilization variable in slid-ing modes of relay regulators optimum in sense of minimization quadratic functional of quality. They are subordinated to the top level realized in a class of analytical extreme systems. The criterion functions describing distribution of reactive power between stator and rotor by circuits AGC are received, their extreme properties are studied, the algo-rithms of extreme control constructed. The stability AGC in a mode generation of reac-tive power in a network is studied, the boundary of stability on a reactive current of a rotor is determined and the mode of removal of auto fluctuations of a basic vector flux linkage is offered.
