In this paper, the leader-following consensus problem for multi-agent linear dynamic systems is considered. All agents and leader have identical multi-input multi-output （MIMO） linear dynamics that can be of any order, and only the output information of each agent is delivered throughout the communication network. When the interaction topology is fixed, the leader-following consensus is attained by Ho~ dynamic output feedback control, and the sufficient condition of robust controllers is equal to the solvability of linear matrix inequality （LMI）. The whole analysis is based on spectral decomposition and an equivalent decoupled structure achieved, and the stability of the system is proved. Finally, we extended the theoretical results to the case that the interaction topology is switching. The simulation results for multiple mobile robots show the effectiveness of the devised methods.

For the single phase inductance-capacitance-inductance(LCL) grid-connected inverter in micro-grid, a kind of robust iterative learning controller is designed. Based on the output power droop characteristics of inverter, the current sharing among the inverters is achieved. Iterative learning strategy is suitable for repeated tracking control and inhibiting periodic disturbance, and is designed using robust performance index, so that it has the ability to overcome the uncertainty of system parameters. Compared with the repetitive control, the robust iterative learning control can get high precision output waveform, and enhance the tracking ability for waveform, and the distortion problem of the output signal can be solved effectively.

产权关系决定着劳动关系的性质和特点,单一的资本产权及由此所形成的生产关系是民营企业劳动关系不和谐的根本原因。调整民营企业劳动关系的关键在于突破原有单一的资本产权制度,建立和完善全体生产要素所有者联合体与劳动者集体联合体有机结合的联合产权制度,形成以知识劳动者为代表的全体劳动者共享民营企业经济发展成果的机制。

邓小平同志在他晚年的"政治交代"、"经济改革交代"之后,更多关注的是中国经济发展起来之后如何再发展的问题,暨如何实现社会主义原则的共同富裕,社会财富如何实现公平分配。对这一重大而充满现实主义精神命题的大智慧思考,在共和国经济史上和社会主义政治经济学史上可称之为"小平之虑"。要从根本上解决这一问题,必须回到马克思劳动价值这一经典理论上去,以马克思劳动价值论的基本思想指导当代社会主义经济实践,这是当代马克思主义政治经济学中国化的核心命题之一,对进一步深化经济体制改革、实现和谐民生具有重大的理论意义和实践价值。
