Energy systems, suffering from various uncertainties, is challenging to control through the conventional controls derived from motion or chemical process control. This talk will first formulate the energy control difficulties in terms of dual objectives, various uncertainties and intractable dynamics such as time-delay, non-minimum phase and multivariable couplings. To this end, an Active Uncertainty Compensation Based Control (AUCBC) scheme will be introduced next, in which a two-degree-of-freedom idea will be used to decouple the missions of uncertainty compensation and set-point tracking. A new two-degree-of-freedom PI controller parameter tuning is proposed to achieve optimal disturbance rejection. Various modifications of AUCBC are proposed individually for the time-delay, non-minimum phase, unstable and multivariable processes. In the end, the theoretic results are experimentally validated by some genuine applications in power plant and fuel cell control.
