Optimization of the Motors for the Control of the CVT Servo-Pumps

The aim of this project is the design and the optimization of the electrical motors used in the Continuously Variable Transmission (CVT) system currently under development at JTEKT, an automotive part supplier company. Two motors are needed for the control ...

Innovative standstill position detection combined with sensorless control of synchronous motors

Jan Persson

Sensorless control of PMSM's (Permanent Magnet Synchronous Motors) has occupied scientists for a long time. The result of this research is becoming widely accepted by the industry due to its low cost and reliability. However, the majority of today's motor ...

SpiderCrane: Model and Properties of a Fast Weight-Handling Equipment

Dominique Bonvin, Philippe Müllhaupt, Davide Buccieri

A new crane design, labeled "SpiderCrane", is proposed to handle fast load displacements. Its main particularity is the absence of heavy mobile components. The system beeing underactuated, its control is challenging. Hence, as a step towards easier and mor ...

Voltage stresses on PWM inverter fed induction motors : cable modeling and measurement.

Jean-Jacques Simond, Basile Kawkabani, Roland Wetter

The present paper deals with the determination of voltage stresses on PWM inverter fed induction motors by considering first the cable modeling and the measurement of different parameters. Then, based on this model, voltage stresses on the motor windings a ...

2004

To design actuators or motors requires analyzing a lot of parameters such as length, temperature, efficiency, weight, etc. To obtain the optimum results for given specifications the solution is to analyze globally all the free parameters in one go, with an ...

Steady state Kalman filtering for sensorless control of hybrid stepper motors

Yves Perriard, Jan Persson

Extended Kalman filtering techniques have been successfully used as sensorless control schemes on many different types of synchronous motors. One big disadvantage of the extended Kalman filtering technique is the large computational cost. Even with today's ...

An Optimized Extended Kalman Filter Algorithm for Hybrid Stepper Motors

Yves Perriard, Jan Persson

In this article a high performance Extended Kalman filter algorithm is used to estimate rotor speed, rotor position and load torque in a Hybrid Stepper Motor (HSM). Together with a PI speed controller, the Kalman filter forms a very robust sensorless close ...

MPC fault-tolerant flight control case study: Flight 1862

Colin Neil Jones

We demonstrate that the fatal crash of El Al Flight 1862 might have been avoided by using MPC-based fault-tolerant control. Simulation on a detailed nonlinear model shows that it is possible to reconfigure the controller so that the aircraft is flown succe ...
