Clean high-energy density renewable power generation systems with soft-switching sliding mode control laws

This paper reports the design, analysis, evaluation and characterization of closed-loop clean renewable power generation systems. For the aforementioned multi-input/multi-output systems, we design proportional-integral and soft-switching sliding mode control laws to guarantee: (1) Efficient mechanical-to-electrical, electrical-to-electrical and electrical-to-chemical energy conversions; (2) Enabling wind- or hydro-energy harvesting capabilities; (3) Optimal dynamics, robustness and stability. The prototypes of portable high-energy-density power systems were tested, characterized and evaluated. We advanced energy sources, enabled electric machinery, and improved power electronics solutions. Linear and nonlinear control algorithms were designed, implemented, and verified. The developed closed-loop clean power generation systems were tested in enhanced operating envelopes. These scalable systems can be used as mini-scale, light- and medium-duty auxiliary, portable and self-sustained power systems in various applications, such as, aerospace, automotive, biotechnology, biomedical, communication, marine, robotics, etc.
