Comparative analysis of agile control system for a downdraft gasification with CHP system
Abstract
Biomass gasification features a feasible and sustainable option to move forward as a net carbon-negative energy technology. Its maturity and capability to produce hydrogen-rich syngas make it sensible to supersede conventional fossil fuel as clean energy source. In this work, a previously developed empirical model of biomass gasification with CHP system is embedded with PID and MPC algorithms. The agility and robustness of the proposed PID and MPC are demonstrated through the servo and regulatory problems which translated by the intermittent power output. MPC exhibits superior control performance with minimal overshoot and diminutive oscillation compared to PID controller. The outcomes obtained from present study are valuable in identifying the feasibility of PKS gasification with CHP system as a sustainable and clean technology.
