Abstract:

The study is based on the use of the discrete time equalizer method for the synthesis and practical implementation of an automatic speed control system of a direct current electric drive. A laboratory research bench was created to carry out experimental research. The synthesis of automatic control systems by the discrete time equalizer method differs from the traditional subordinate coordinate control or the generalized characteristic polynomial method in complete rejection of the use of the desired characteristic polynomials. This approach allows obtaining the desired dynamic and static properties of the system solely on the basis of the desired transition function, which should be close to the natural character of the transition processes (monotonic, aperiodic or oscillatory). The Code Composer Studio integrated design environment allows practical implementation of the proposed discrete time equalizers, the inverse model of the control object, and the inverse transformation modification unit in the form of special routines for the Texas Instruments TMS320F28335 microcontroller – macros in the C/C++ programming language.The main body of the control program, constructed in accordance with the developed functional diagram of macros interaction, made it possible to carry out the experimental studies using both the main control channel with one discrete time equalizer and the combined control with two discrete time equalizers (main and compensating). Since the entire program code used in the research was written in the high-level programming language C/C++ using object-oriented approaches, it is hardware independent of the microprocessor type and can be transferred easily to another hardware base Author Biographies Oleksii Sheremet, Donbass State Engineering Academy Akademichna str., 72, Kramatorsk, Ukraine, 84313 Doctor of Technical Sciences, Associate Professor Department of Electromechanical Systems of Automation and Electric Drive
