员工竞优行为作为一种有效的优势干预和自我价值实现途径,是应该被组织倡导的行为.本文将竞优行为置于工作情境中,运用扎根理论的方法,基于认知理论构建了员工竞优行为的影响因素模型.研究结果表明:员工通过对外部匹配环境(个人-组织匹配)的感知和自身的调控系统来强化对竞优活动的认知,进而影响竞优行为,其中个体对竞优的认知因素包括对工作价值的认知、对竞优自主动机的认知和对竞优自我效能感的认知;竞优行为的形成和强化是由认知因素直接驱动的,在此过程中,外部支持性的环境(竞优氛围与文化和工作特征)起到调节作用.研究结论揭示了员工竞优行为的影响因素和作用机理,为组织激励员工竞优行为提供了可参考的依据.

本文针对企业战略管理的新价值理念,以竞优思想为指导,构建了基于现代企业管理的有力工具——标杆学习的企业战略行为调整的一种新方法与其应用范例.从选择标杆、向标杆学习到确立调整方案,在该方法的全过程中采用了个体优势特征识别、个体及民主代理评价等竞优评析理论,因此,所得到的标杆就是竞优标杆,而且所产生的调整效果就是企业战略行为的竞优调整效果.本文研究过程中提出的理论、方法和对中国钢铁行业内一个上市公司的应用研究都具有公正性、客观性、易被接受性,并且所得到的分析及评价结果都可为企业战略的顺利运行和实现其最终目标提供方向性辅助与技术支持.

Model predictive control(MPC) is a kind of novel control algorithm which is based on the model of the controlled system. This method can predict the future state of the system, and the optimal control variables can be obtained by the rolling optimization, and it has excellent performances and with hard robustness. In the traditional flux weakening control method based on the voltage closed-loop control strategy, the performances of the system are usually affected by the coefficients of the PI regulators and the accuracy of motor parameters. A novel flux weakening method based on MPC is proposed in this paper to solve these problems. The implementation process of the proposed method is described in detail. By optimization this method is suitable for the real-time control of motor. The experimental results prove that the MPC method has a quick response and with hard robustness. MPC method have better performances than PI method against load disturbance, and it's very suitable for the induction motor flux-weakening control in high-performance occasions.

This paper proposed a novel flux weakening scheme based on model predictive control (MPC) for induction motor applied in electric wheel. This control method is implemented based on the voltage control strategy, where model predictive control (MPC) algorithm other than traditional PI regulators is adopted to adjust the flux current component. Experimental results on an experimental platform are given to verify the effects of the proposed method. By rolling optimization of MPC, quick response and little overshoot can be realized in the flux weakening control, proper d-axe current can be got by the proposed MPC flux weakening control method according to the current speed and load, it also has a good capability with torque disturbance. This method is very suitable for the control of induction motor.

The optimal flux weakening methods for Induction Motor are mainly based on the closed loop control of the motor stator voltage. The performances of the system are usually affected by the coefficients of the PI regulators,which are hard to obtain. A novel flux weakening method based on MPC is proposed in this paper to solve these problems,by optimization this method is suitable for the real-time control of motor. A test bench was built to verify the performances of the proposed method. The experimental results prove that the MPC method has a quick response and with hard robustness,MPC method is very suitable for different application of Induction motors.
