Model predictive control of a DC–DC converter for battery emulation

摘要: Abstract A battery emulator is used instead of a real traction to supply an electric motor inverter on test bed for hybrid and powertrains under deterministic conditions. The use virtual models eliminates the need expensive prototypes. Virtual properties such as chemistry, state charge or health can be changed instantly. However, control challenging problem. Very fast reference tracking required impedance emulation but inverters act constant power loads that have negative influence performance even lead instability. In this paper MPC strategy proposed solving Scheduling local controllers utilized in order handle nonlinear destabilizing load. Furthermore, algorithm presented allows real-time subject input output constraints. Experimental results obtained with supplying drive demonstrate stabilizing controller.
