In an electric vehicle drive control system,speed,current and voltage sensor faults will affect the control performance and reliability.Aiming at these three type sensors fault,this paper presents a multi-sensors fault detection algorithm and fault-tolerant control strategy based on an EKF and a Luenberger state observer.With the proposed algorithm,the drive system is capable of diagnosing these sensor faults immediately and accurately,and reconfiguring the system state by utilizing the rest redundant information,then,an uninterrupted fault-tolerant control is realized effectively.Finally,the control performance and reliability performance of drive system for electric vehicle are enhanced.Experimental results demonstrate the effectiveness of both the fault detection algorithm and the reconfigurable control strategy.

生物神经元同步是生物电生理学研究的热点和难点问题。针对生物神经元同步控制算法大多依据神经元模型设计，存在算法相对复杂、难以实现的不足，本文以Morris-Lecar 神经元为研究对象，设计线性自抗扰控制算法，仅用一个控制输入实现生物神经元的膜电位同步；同时，为考察干扰存在时Morris-Lecar 神经元膜电位的自抗扰同步效果，仿真中加入正弦干扰，线性自抗扰抗控制仍能实现神经元膜电位间的同步。数值
