This paper presents brain emotional controller (BEC)-based adaptive mechanism in Model Reference Adaptive System (MRAS) to control sensorless permanent magnet synchronous motor (PMSM) drive. BEC is a bio-inspired intelligent controller developed using neurobiological connections of mammalian brain by inspiring limbic system. The developed controller is applied as speed controller and parameter estimation (i.e. rotor speed and rotor position) of PMSM drive. The proposed BEC stability is proved to guarantee convergence characteristics. The performance of BEC-based adaptive mechanism is evaluated in simulation environment, and obtained results are compared in real time in hardware-in-loop (HIL) environment. In order to hold the effective performance of the proposed method compared with fuzzy logic controller with similar tests, further integral performances are evaluated for BEC and fuzzy logic controllers. Results demonstrated in HIL and in simulation show applicability, robust and sensitiveness of the proposed BEC method.

本文介绍了模型参考自适应系统 (MRAS) 中基于大脑情绪控制器 (BEC) 的自适应机制，以控制无传感器永磁同步电机 (PMSM) 驱动。BEC是一种仿生智能控制器，利用哺乳动物大脑的神经生物学连接，通过启发边缘系统而开发。所开发的控制器被用作永磁同步电机驱动的速度控制器和参数估计（即转子速度和转子位置）。证明了所提出的 BEC 稳定性可以保证收敛特性。在仿真环境中评估基于 BEC 的自适应机制的性能，并在硬件在环 (HIL) 环境中实时比较所得结果。与类似测试的模糊逻辑控制器相比，为了保持所提出方法的有效性能，进一步评估了 BEC 和模糊逻辑控制器的整体性能。在 HIL 和仿真中证明的结果表明了所提出的 BEC 方法的适用性、鲁棒性和敏感性。
