Application of Power Amplifier OPA544 in Active Magnetic Bearing Control System

摘要：

Adopt device power amplifier OPA544 to amplify the output load current in order to achieve the systems current increase. According to the completed mechanical analysis and the design of this specific active magnetic system, the controlling model was designed and a PID controlling strategy was selected to achieve a system simulation utilizing the whole module’s parameters. To control the suspension, a PID controlling circuit was designed to attain the full current necessary for maintaining lift. The use of two electronic OPA544 chips allows for push-pull power amplifier control, achieving the establishment of active magnetic plate dynamic equilibrium, as well as better system stability. Experimental data from the study supported the simulation. The system designed represents a practical model based on experimental data. These methods could be used as a reference for power amplifier component selection among similar systems.
