“…For each ATO configuration, two tests were performed: without adding noise to the resolver outputs, and adding a noise (zero mean and 0.0002 variance) to the resolver outputs. Figures 9,10,11, 12 and 13 show the angle estimation error for each simulation test. Table 3 shows the root mean square error (RMSE) and the error settling time (the time required for the error signal to achieve its steady-state value) for each simulation test.…”

“…However, most sensorless techniques depend on motor parameters whose values cannot be measured with accuracy. Hence, sensorless techniques have angular estimation errors [11]. As a result, many applications such as electric vehicles, antennas, and servomechanism still depend on sensors to guarantee precise angular position information [11][12][13][14][15][16].…”

High-performance motor drives that operate in harsh conditions require an accurate and robust angular position measurement to correctly 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 developing 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 literature approaches.

“…Permanent magnet synchronous motor (PMSM) has been widely used in pounds of industrial fields due to its small size, high efficiency and good speed regulation. [1][2][3] But in the actual operation of PMSM, the load torque and rotational inertia will change frequently, which will affect the performance of the control system. 4 In order to achieve high performance, it is necessary to improve the robustness to parameter changes and enhance the anti-interference abilities of the system.…”

To enhance the anti-inertia disturbance ability of permanent magnet synchronous motor (PMSM) speed system, an adaptive sliding mode control with inertia identification is proposed. A novel sliding mode control (NSMC) based on a new reaching law coupled with model reference adaptive system (MRAS) inertia identification is realized the adaptive control, named MRAS+NSMC. In the NSMC construct process, an integral sliding mode surface and a variable speed reaching law are introduced to avoid speed differentiation and improve dynamics, respectively. And the new reaching law imported a successive sigmoid( s) to replace the traditional sign( s) to suppress chattering phenomena. For the problem that the performance deteriorated by rotational inertia variation caused by load changes, the inertia is estimated in real time according to the MRAS theory, and the identification value is updated to the NSMC controller to realize adaptive MRAS+NSMC speed control. Experimental results show that the proposed adaptive MRAS+NSMC control has a faster speed response, and the speed response time is reduced from 85 to 49 ms compared with conventional SMC control. In addition, it has strong robustness to inertia disturbances and high speed tracking accuracy. Compared with conventional SMC, the speed tracking accuracy of proposed MRAS+NSMC is increased from 12% to 4%. This makes the proposed MRAS+NSMC control has great potential practical significance for speed control of PMSM.

“…This approach leads to a cheaper, more reliable, and more versatile system. Most common software-based RDCs are designed taking into account Phase Locked Loop (PLL) [12]- [13] or Angle Tracking Observer (ATO) algorithms [14]- [15]. Also with this approach, the hardware interface presents a complex structure with a high number of electronic components that result in expensive implementation.…”

In this paper, a software-based resolver to digital converter (RDC) is proposed. The hardware signal conditioning circuit is realized using common electronic components, while the algorithm can be implemented either using a microcontroller or an FPGA. Its validation and performance analysis has been carried out using an interior permanent magnet synchronous machine drive and, with comparative purposes, an LTN Servotechnik 1024 ppr incremental encoder. Tests show that the proposed RDC is characterized by a good dynamic response and precision, moreover, due to low computational demand, it can be successfully adopted without significant extra cost.
