Constrained design and control of trapezoidal waves‐forms hybrid excitation synchronous motor increasing energy accumulator lifetime

Abstract

Summary In this paper, we present a methodology of systemic design and control of an axial synchronous motor structure with hybrid excitation. This structure is with reduced manufacturing cost, since it is with straight and opened slots and with concentrated winding. The coils can be inserted in a single block. This methodology is based on the analytical method producing solutions without iterations and compatible with optimization approaches. Finally, a robust control algorithm of the studied engine compatible with this design approach is developed, as well as implanted under the Matlab‐Simulink simulation environment. The results of simulations found are with good scientific level and encourages the industrialization of the global studied system.

Methodology for optimal design and control of wind energy system based on simplifying assumptions

“…The wind energy generator is designed by the analytical method using the same equations of an axial motor with permanents magnets by changing some inputs to have a generator structure. Indeed, the inputs of the generator analytical design model are Neji et al (2006), Tounsi and Abdallah (2020), and Tounsi (2019):…”

“…The chosen design method is analytical one, since it is flexible to provide solutions based on the power requirement. This method is based on general theorems of design of electrical device as on simplifying assumptions justified (Neji et al, 2006; Tounsi, 2019; Tounsi and Abdallah, 2020).…”

“…The height of magnets (H a ) necessary for a magnetic induction in the gap B e is derived by applying the Ampere theorem on a closed contour at a tooth (Neji et al, 2006; Tounsi, 2019; Tounsi and Abdallah, 2020):…”

“…The height of the stator yoke is calculated by applying the flow conservation theorem for a maximum flux position in the cylinder head (Neji et al, 2006; Tounsi, 2019; Tounsi and Abdallah, 2020):…”

“…The expression of the magnitude of the induced back electromotive forces is as follow (Neji et al, 2006; Tounsi, 2019; Tounsi and Abdallah, 2020):…”
