This paper presents novel maximum torque per ampere (MTPA) and power (MPPA) sliding mode control (SMC) approaches for interior permanent-magnet synchronous motors (IPMs). We first derive the first-order SMC methods to improve field-oriented control's resiliency against external perturbations, extraneous noise modelling uncertainties. After that, we propose higher-order significantly reduce chat...

Recently, Inner permanent magnet (IPM) synchronous machines have been introduced as a possible traction motor in hybrid electric vehicle (HEV) and traction applications due to their unique merits. In order to achieve maximum torque per ampere (MTPA), optimization of the motor geometry parameters is necessary. This paper Presents a design method to achieve minimum volume, MTPA and minimum ...

Permanent magnet synchronous motors (PMSM) are known for their type whose magnets located on the rotor surface and this motor type, which is called mounted (SPM), generates torque due to rotor. Based equations, since there only q axis current value of magnetic flux linkage, d kept at 0 maximized controlled, I_d = control technique. However, reluctance generated in interior permanent (IPM) induc...

This article presents a maximum torque per ampere strategy for five-phase synchronous reluctance drive. The approach is developed considering general machine parameters and formalized as constrained optimization problem. optimal solution found analytically by using Lagrange’s multipliers method based on the computation of eigenvalues eigenvectors inductance derivatives matrix. proposed evaluate...

This paper proposes an extended-flux model with core-loss resistance of SynRMs (synchronous reluctance motors) and precise torque estimation without core-loss measurement and position encoder. The proposed torque estimation is useful for precise MTPA (maximum torque per ampere) control of position sensorless controlled SynRMs, which is achieved with the assistance of active and reactive powers.

The high-frequency signal injection-type maximum torque per ampere (MTPA) algorithm is usually employed to control the operation of interior permanent magnet synchronous motors (IPMSMs). MTPA exhibits good dynamic performance and anti-interference ability. However, due injection a current signal, problems such as ripple additional loss are encountered. Therefore, in this paper, virtual (VSIC) m...

The optimal feedforward torque control problem is tackled and solved analytically for synchronous machines while stator resistance and cross-coupling inductance are explicitly considered. Analytical solutions for the direct and quadrature optimal reference currents are found for all major operation strategies such as Maximum Torque per Current (MTPC) (or often called as Maximum Torque per Amper...
