DOMINGUEZ, Xavier; POZO, Marcelo  and  ORTEGA, Leonardo. Control of an electric traction system by means of cascade scheme regulation and machine vector control. Rev Politéc. (Quito) [online]. 2017, vol.39, n.2, pp.27-32. ISSN 2477-8990.

The aim of this paper is the control of an electric traction system. Firstly, the operation of the half-bridge bidirectional DC-DC converter employed for this kind of applications is detailed. Secondly, the control of the system is proposed by using a cascade control scheme. Later, by means of a three-leg three-phase inverter that employs a pulse width modulation strategy, the torque and speed control is achieved for a Surface Permanent Magnet Synchronous Machine (SPMSM). Vector control is also used to achieve this goal. The results exhibit successful responses for both, dynamic and steady state, for operation in motor mode and energy regeneration mode.

Keywords : Bidirectional DC-DC converter; Cascade Control; Machine Vector Control; SPMSM.
