Experiment Oriented Closed-loop Speed Control Design for Induction Motor Based Industrial Blower

In this paper, a real time speed control of induction motor with system simulation of common industrial machines is proposed. The propose using an industrial blower prototype with a three-level inverter for system simulation. This propose is the first step of implementing cyber-attack on industrial machines. Recent cyber-attacks on industrial power systems (Stuxnet and Ukrainian power grid) clearly point out the recent trend of digital battlefield. The potential damage caused by successful malicious act to such systems is much more severe than any other experienced by far. Possible cyber-attack in industrial field will aimed to damage cooling systems by striking the motors behind. The blower’s parameters were estimated using experiments for model approximation of motor parameters and load. Close-loop control is based on DSP and industrial encoder. The proposed can be used for further implementing malware in cyber-attack on low level control.
