FPGA-based delay compensation on model predictive control for a PM synchronous machine

This paper presents the cosimulation of the model predictive control (MPC) for a permanent magnet synchronous machine (PMSM) based on the technology of field programmable gate array (FPGA). One of the problems that occurs during the digital implementation of MPC control schemes due to its high computational burden is a time delay from the moment in which the controlled variables are sampled and the moment in which the control action is applied, this delay can affect the performance of the system if is not taken into account. To overcome this problem this paper presents a simple delay compensation based on the mathematical model of the machine. Simulations results using hardware description are presented in order to point out the effects of the delay introduced and to validate the presented delay compensation technique.
