In this paper, a constrained model predictive controller with guaranteed stability is proposed for a PEM fuel cell. The aim is to prevent oxygen starvation by controlling the air supply system, when the control system is affected by required stack current as a measurable disturbance. The compressor voltage is controlled to regulate the oxygen excess ratio towards a desired equilibrium to avoid oxygen...
This paper proposes a modified stationary reference frame-based predictive current controller with zero steady-state error for LCL coupled inverter-based distribution generation systems. Analytical expressions for the predictive current control error sources are investigated. The stability margin for the predictive current gain is derived. Online adaptive control for the grid voltage is embedded in...
This paper presents a discrete-time predictive control strategy for a voltage-source inverter based on computation of a deadbeat control law and its approximating suboptimal voltage vector at every sampling interval. The controller, in addition to compensating for the inherent delay in the system, employs a simple prediction filter to suppress the disturbance caused by the back-EMF voltages and improve...
