Permanent Magnet Synchronous Machine Hybrid Torque Control [PDF]
IEEE Transactions on Industrial Electronics, 2008 This paper presents a control scheme suitable for systems composed of a continuous process modulated in energy by a power converter with a finite number of topologies. To track the continuous reference values, a topology of the power converter is determined from a criterion based on a process state variable model and taking into account the possible ...
