A DSP-based real-time simulation equipment for fast motor control development
No full text"This work presents a rapid motor control prototyping technique based on the development of a real-time simulation environment structured on a DSP architecture. The considered case study refers to an Interior Permanent Magnet synchronous motor (IPM) drive arranging a field oriented speed control with the optimization of the torque-to-current ratio and the decoupling of the feeding voltages. The main topics of this work are related with the construction of the real-time simulation platform and with the implementation issues coming from the use of a hardware DSP-based setup. In particular it will be shown how such a kind of simulation architecture can model very closely the real behaviour of a controlled IPM drive and consequently how it can be used to properly tune the control algorithm without the needing of using the real motor drive saving this way a lot of deployment time."This work presents a rapid motor control prototyping technique based on the development of a real-time simulation environment structured on a DSP architecture.

Analysis of phase-detection algorithms for back-EMF-based sensorless strategies through real-time simulations
No full textThe work developed in this paper presents a comparison between three different phase detection algorithms in order to study the benefits of using each of them when they are applied inside a sensorless rotor position estimation technique. In particular we will analyse the various aspects related to the use of each single algorithm when it is applied into a specific model-based sensorless strategy and when we also take into account the typical impairments affecting the implementation of the real setup, such as unwanted harmonic components and measurement offsets.
As a first step a short overview on the phase-detection algorithms under consideration will be given and subsequently the proposed model-based estimation technique is presented, that are suitable for different machines. As a second step the three algorithms are analyzed in detail highlighting their dynamical performances and their robustness properties against implementative knots, in particular through the use of software simulations and real-time simulations reproducing the specific test case of a five-phase motor.The work developed in this paper presents a comparison between three different phase detection algorithms in order to study the benefits of using each of them when they are applied inside a sensorless rotor position estimation technique.

Flux-Weakening Control of Surface Mounted PM Synchronous Motors Accounting for Resistive Voltage Drop
No full textThis paper deals with the flux-weakening control of surface mounted permanent magnet synchronous motors, taking into account the influence of the resistive voltage drop in the stator windings, an effect which is usually neglected in similar studies. At first, the motor equations exploiting the optimal torque-speed limits in the flux-weakening region are evaluated and discussed. Then, the influence of the resistive voltage drop is pointed out, evidencing the mismatches related to its neglecting in the set-up of the flux-weakening strategy. Hence, a simplified approach to flux-weakening motor control is presented, useful for the practical implementation in micro-controlled drives. Finally, experimental results are shown, using a position-tracking application as a test case
Sensorless Control of PM Synchronous Motors with Luenberger Observer: Theoretical Issues and Implementation Results
No full textAnalysis of fault-tolerant PM motors with independent phases by finite element method
No full textThis paper presents the finite element analysis of a multiphase permanent-magnet motor designed to have independent phases structure according to the principles of fault tolerance. The goal of the study is to verify and quantify the independence of the phases from the electromagnetic point of view, one of the key requirements of fault-tolerant machines. The case study refers to a five-phase permanent-magnet motor designed for an aircraft flap application. The typical operating conditions of motors designed to operate in fault tolerant environments are considered, such as the opening of one or more phases after the occurrence of a failure. The actual performance of the multiphase motor is compared to that achieved by the superposition of the effects of each phase fed independently, which is the straightforward approach in usual modeling. The results demonstrate that modeling by independent phases leads to negligible errors in almost all the operating conditions
