The Control System of the Electric Drive Mechanism for Lifting the Shutter of a Drainage Dam Using Fuzzy Logic

The work is dedicated to the modernization of the current system of the electric drive of the mechanism for lifting the spillway dam. An expert system with fuzzy logic is used to perform the processes of starting, starting and moving the drain dam shutter, which takes into account the current state of the electric drive system during the technological operation and forms the necessary frequency control law for starting and further guaranteed start of the electric drive of the technological mechanism. The influence of fuzzy logic rule coding methods on the formation of the output signal for controlling the power devices of the electric drive system is considered. It was established that the starting and starting processes in the proposed electric drive system, in contrast to controlled starting systems with a rigidly defined frequency control law, are characterized by a longer start-up process duration, but lower thermal and vibrational loads on the EP system due to the controlled formation of the starting current (torque), which helps preserve the resource of the technological mechanism as a whole.
