Direct Torque Control for Switched Reluctance Motor to Obtain High Torque–Ampere Ratio

IEEE transactions on industrial electronics (1982. Print), 2019
The direct torque control (DTC) method was introduced into the switched reluctance motor to reduce its inherent output torque ripple. However, the conventional DTC method produces negative torque more or less, which reduces the torque–ampere ratio of ...

Maximum Torque Per Ampere (MTPA) Control for IPMSM Drives Based on a Variable-Equivalent-Parameter MTPA Control Law

IEEE transactions on power electronics, 2019
This paper presents a maximum torque per ampere (MTPA) control method for interior permanent-magnet synchronous motor drives. The proposed method employs a variable-equivalent-parameter MTPA control law to calculate the MTPA current references. Different

Real-Time Maximum Torque per Ampere Control of Brushless DC Motor Drive With Minimum Torque Ripple

IEEE transactions on power electronics, 2020
A nonlinear control scheme is proposed for real-time tracking of maximum torque per ampere trajectory of the surface-mounted brushless dc motor with non-sinusoidal back electromotive force (back-EMF). The strategy employs the Lagrange's Theorem to obtain

Maximum Torque per Ampere (MTPA) Control for IPMSM Drives Using Signal Injection and an MTPA Control Law

IEEE Transactions on Industrial Informatics, 2019
This paper presents a maximum torque per ampere (MTPA) control scheme for interior permanent magnet synchronous motor drives. In this scheme, an enhanced signal injection technique is responsible for correcting the MTPA reference deviation due to motor ...
