MICROPROCESSOR CONTROL OF TWO MASS ELECTROMECHANICAL SYSTEM

Abstract

All lifting mechanisms operate in a cyclic mode. It is important that these mechanisms operate in a constant mode. The time of their transients is relatively short, due to the fact that the moment of inertia of all working elements with the load reduced to the motor shaft is 8-12% of the moment of inertia of the motor rotor together with the clutch and brake pulley. Dynamic moments in transients are transmitted through kinetic links, significantly loading them. The elements of the transmission device from the engine to the working body and the metal structure are characterized by elasticity and the available backlash in the gears. Control and disturbances in such electromechanical systems cause transients associated with the exchange of energy between its links, create vibrations, reduce the accuracy of installation and quality of operations and cause additional loads in the links of the kinematic circuit. The possibility of microprocessor control of start-up of electromechanical system with backlash with simultaneous restriction at the arising at the same time dynamic loadings in kinematic links is considered. An algorithm and a program for controlling an industrial controller are proposed. The simulation results are given. The purpose of the work is to demonstrate the possibility of microprocessor control of the start of the electromechanical system with backlash, which provides the minimum time of transients and damping of oscillations of the suspended load with simultaneous restriction at the resulting dynamic loads in the kinematic links. The task of this work is to develop a program for an industrial controller in accordance with the control algorithm
