Guide-line for the PM Linear Synchronous Motors design
No full textA guideline for the design of PM Linear Synchronous Motors is proposed. It allows to find the main motor dimensions for a given thrust and linear speed. In order to verify the accuracy of the proposed design procedure, an accurate 2-D Finite Element model of the LSM has been carried out. An example has been presented and the results have been compared with the FEA ones: the comparison points out a good concordance and confirm the goodness of the approach
High performance AC drives using passivity based controllers
No full textThe energy-based approach, also known as “passivity based”, is becoming a popular nonlinear control method allowing precise and stable control of the induction motor and more in general of AC motors. Its main features are: simple formulation; the actual possibility of the use of inexpensive microprocessors for its implementation; its global stability in the whole operating range including zero speed region; satisfactory tracking capabilities of position, speed, torque and flux; and high robustness in case of parameter variations. This paper, after a short theoretical background presents and discusses several experimental result
