“…In [35], it was proposed for the first time the application of the conventional GPC described in [22] in the development of an ATO. In that approach, the ATO was modelled as a tracking system where the reference is the actual angular position and the system output is the estimated angle.…”

“…Thus, the angle estimation is represented as a tracking problem. However, the ATO proposed in [35] has a steady-state angle estimation error during constant speed operation. In order to explain this error, let define R(s), G(s) and C(s) be, respectively, the transfer function of the reference, the plant transfer function and the controller.…”

“…Besides, the Laplace transform of a ramp signal is 1/s 2 . However, the conventional GPC system used in [35] has only one embedded integrator (1/s). Furthermore, the GPC cost function used in [35] considers that the reference signal is constant for the predicted outputs, which is false when the reference is a ramp signal.…”

“…In order to develop an ATO with the advantages of the GPC and with a zero steady-state angle estimation error during constant speed operation, this paper proposes an ATO based on the second-order difference generalized predictive control (SOD-GPC) described in [39]. As in [35], the ATO is modelled as a tracking system whose reference is the actual angular position and whose output is the estimated angle. During constant speed operation, the angular position (the reference) is a ramp signal.…”

High-performance motor drives that operate in harsh conditions require an accurate and robust angular position measurement to properly estimate the speed and reduce the torque ripple produced by angular estimation error. For that reason, a resolver is used in motor drives as a position sensor due to its robustness. A resolver-to-digital converter (RDC) is an observer used to get the angular position from the resolver signals. Most RDCs are based on angle tracking observers (ATOs). On the other hand, generalized predictive control (GPC) has become a powerful tool in the development of controllers and observers for industrial applications. However, no GPC-based RDC with zero steady-state error during constant speed operation was proposed. This paper proposes an RDC based on a second-order difference GPC (SOD-GPC). In SOD-GPC, the second order difference operator is applied to design a GPC model with two embedded integrators. Thus, the SOD-GPC is used to design a type-II ATO whose steady-state angle estimation error tends to zero during constant speed operation. Simulation and experimental results prove that the proposed RDC system has better performance than other approaches in literature.
