A Sensorless PM Synchronous Motor Drive for Electric Washers
Communications, 2007 This paper presents a complex solution for whole speed range sensorless control of interior permanent magnet synchronous motor drives. To cover an entire speed range of IPMSM without position transducer, different sensorless techniques must be employed ...

Recent developments in sensorless and quasi‐sensorless drive
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2002 There are two main types of speed/position sensorless closed‐loop variable‐speed electrical drives: sensorless and quasi‐sensorless drives. In sensorless drives, the classical speed and position sensors (transducers) are absent and are replaced by mathematical‐model‐based and/or artificial‐intelligence‐based estimators.

Almost-Sensorless Localization [PDF]
Proceedings of the 2005 IEEE International Conference on Robotics and Automation, 2006 We present a localization method for robots equipped with only a compass, a contact sensor and a map of the environment. In this framework, a localization strategy can be described as a sequence of directions in which the robot moves maximally. We show that a localizing sequence exists for any simply connected polygonal environment by presenting an ...

Sensorless stabilization of bounce juggling [PDF]
IEEE Transactions on Robotics, 2006 The paper studies the properties of a sinusoidally vibrating wedge billiard as a model for 2-D bounce juggling. It is shown that some periodic orbits that are unstable in the elastic fixed wedge become exponentially stable in the nonelastic vibrating wedge.

Position estimation delays in signal injection-based sensorless PMSM drives [PDF]
, 2012 The causes of position estimation delays and their effects on the sensorless control of permanent magnet synchronous motor drives are investigated. The position of a permanent magnet synchronous machine is estimated via the injection of high frequency ...

End effects in linear tubular motors and compensated position sensorless control based on pulsating voltage injection [PDF]
, 2011 The sensorless position control of permanent-magnet (PM) synchronous motors can be successfully implemented by superimposing a high-frequency voltage signal on the control voltage.

Sensorless Torque/Force Control [PDF]
, 2011 Motion control systems represent a main subsystem for majority of processing systems that can be found in the industrial sector. These systems are concerned with the actuation of all devices in the manufacturing process such as machines, robots, conveyor systems and pick and place mechanisms such that they satisfy certain motion requirements, e.g., the

Self-Commissioning Algorithm for Inverter Non-Linearity Compensation in Sensorless Induction Motor Drives [PDF]
, 2010 In many sensorless field-oriented control schemes for induction motor (IM) drives, flux is estimated by means of measured motor currents and control reference voltages.

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]
, 2006 Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...
