Sensorless Finite-Control Set Model Predictive Control for IPMSM Drives

Abstract

-This paper investigates the feasibility of a sensorless field oriented control (FOC) combined with a finite control set model predictive current control (FCS-MPC) for an interior permanent magnet synchronous motor (IPMSM). The use of a FCS-MPC makes the implementation of most of the existing sensorless techniques difficult due to the lack of a modulator. The proposed sensorless algorithm exploits the saliency of the motor and the intrinsic higher current ripple of the FCS-MPC to extract position and speed information using a model-based approach. This method does not require the injection of additional voltage vectors or the periodic interruption of the control algorithm and consequently it has no impact on the performance of the current control. The proposed algorithm has been tested in simulation and validated on an experimental setup, showing promising results.

Model Predictive Control for Shunt Active Filters With Fixed Switching Frequency

“…At each sample time FCS-MPC computes a target cost function for every possible control action: the one associated to the minimum cost function value is selected as optimal control and applied [19]. This technique has been successfully applied for the control of three-phase inverters [20], [21], matrix converters [22], [23], power control in an active front end rectifiers [24], [25], and regulation of both electrical and mechanical variables in drive system applications [26]- [30].…”

A Modulated Model Predictive Current Controller for Interior Permanent-Magnet Synchronous Motors

“…Due to its advantages of high reliability, high power density, and minimal noise, the interior permanent-magnet synchronous motor (IPMSM) is regarded as a superior solution in a lot of electrical drives and industry applications [1,2]. The motor is characterized by its unique salient-pole structure for precision operation at diverse speeds.…”

Modulated Predictive Control for Indirect Matrix Converter

“…Matrix converters can minimize the size of the required passives components, thus increasing the potential power density and reliability of the converter [1], [2]. For such reasons Matrix converters are often proposed in high power density applications, such as drive [3], [4], aircraft ground power supply units [5], inductive power transfer [6]- [8] and hybrid transformers [9], [10], as a compact alternative to standard back-to-back AC/AC topologies. Among all the possible topologies in the matrix converter family, the Indirect Matrix Converter (IMC) represents an interesting solution for direct AC-AC power conversion in many applications.…”

“…However, with the rapid development of digital processors and power devices, the use of SVM in conjunction with linear controllers is now being challenged by Model Predictive Control (MPC) [13]. MPC provides numerous advantages over conventional modulation and control methods, such as the capability of achieving several control targets within a single control loop, easy implementation on digital control boards, capability of include constraints in the control system and improved dynamic performance [3], [4], [31]- [34]. MPC has been successfully applied to the IMC to obtain sinusoidal input and output currents, control the input reactive power, increase efficiency and reduce common mode voltages [26], [28], [35], [36].…”
