Design and Analysis of Uninterruptible Power Supply Control Technology for Manufacturing Automation Applications

In this paper, an Uninterruptible Power Supply (UPS) with a robust control technology is proposed for the application of the Manufacturing Automation (MA). The proposed control technology is composed of a Fast Sliding Mode Control (FSMC) and a Glowworm Swarm Optimization (GSO). Although the FSMC guarantees finite system-state convergence time of the UPS, the distorted and unstable UPS output-voltage degrades the unreliability of MA. This is because the inappropriate control parameters exist in UPS system. The GSO is thus employed to tune FSMC control gains optimally, yielding high performance UPS in the use of the MA. Experimental results show that the proposed control technology can lead to high-quality AC output voltage and fast dynamic response. Because the proposed control technology is simpler to implement than previous methods and has higher convergence accuracy, this paper will be of interest to investigators of related MA. 
