DEVELOPMENT AND INVESTIGATION OF NEW SYSTEMS FOR CONTROL OF ROTATIONAL A.C. COMMUTATORLESS MOTOR SPEED

The aim is to develop and design the control systems (CS), to calculate and analyze the statical and energetical characteristics of CS, to develop the supply condition selection methods. The mathematical modelling and experimental test on the physical mock-ups have been performed. The new approachs to the control of the a.c. motors have been proposed. The mathematical models of investigated CS have been created. The methods for selection of the supply condition which is optimum according to the removed rower level have been developed. The proposed CS have a simple control algorithm and don't require the application of the power reactive elements. The developed algorithmic facilities and software permit to calculate the statical and energetical characteristics of the drives, to optimize the supply condition. The developed software is used at designing prototype of the induction motor CS. The application of developed control systems will permit to improve the mass-dimensional values and to increase the drive operation reliabilityAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
