“…This behavior limits their usefulness with complex control algorithms and very fast direct current controllers. A new alternative to implementing control algorithms on DSPs is the use of field programmable gate arrays (FPGA), offering very fast calculation times and parallel computing capabilities [19]. This paper introduces a new FPGA based direct current control algorithm for grid connected inverters.…”

Abstract-The accurate control of the line current, robust and dynamic behavior even under distorted grids and other system faults are the most important requirements for grid connected inverters. Applying direct current control to multilevel inverters combines the advantages of both and is an enabling step towards improved inverter performance. Direct current controllers suffer from high complexity at increased level count, which is resolved using geometrical principles and simple analytical calculations for switching vector selection within the space vector diagram. The simplified, novel parametric controller concept is scalable to inverters with arbitrary level count, does not require any switching tables and the new fully symmetric setup guarantees equal switching frequencies among the three phases. The hypotheses are further confirmed on a real hardware test setup on the example of a 3-level NPC inverter hardware and a Xilinx development platform. Experimental results prove the expected behavior of the direct current control under various conditions, shows a general approach to balance the DC-link capacitors of diode-clamped inverters within the theoretical limits and demonstrates the benefits of using Field Programmable Gate Arrays (FPGA) as a controller platform.

This paper presents a model predictive torque control method for electrical drive systems. A two-step prediction horizon is achieved by considering the reduction of the torque ripples. The electromagnetic torque and the stator flux error between predicted values and the references, and an over-current protection are considered in the cost function design. The best voltage vector is selected by minimising the value of the cost function, which aims to achieve a low torque ripple in two intervals. The study is carried out experimentally. The results show that the proposed method achieves good performance in both steady and transient states.

“…In [11], Lin et al utilized an FPGA to implement a complete linear induction motor controller. Naouar et al [12] proposed an FPGA-based predictive current controller for synchronous machines. Indeed, with FPGA solutions, it is possible to perform computation tasks in a parallel mode, allowing execution of complex control algorithms within a few micro-seconds.…”
