A Sliding Mode Controller of Permanent Magnet Synchronous Motor（PMSM） is analyzed and designed in this paper. Because of non-linearity, strong couple and disturb sensitivity of PMSM, it is difficult for linear control technology to get perfect control performance of PMSM. Sliding Mode Control（SMC） is an efficient robust control method, which can self-adjust controller structure online, and is non-sensitive to parameter variety and outside disturb. dq Coordinate based rotor reference model of PMSM is built up. Principles and characters of SMC are analyzed in theory. Model and design of SMC of PMSM are deduced in details. Finally, simulation model is built up and various simulations are carried out under MATLAB/Simulink. Simulation results show that SMC is more robust than PI.

冷热电联供型多微网系统日前优化调度需综合考虑源荷的不确定性、微网间热电功率交互及不同利益主体间的博弈。将各微网作为不同的利益主体,利用区间数描述风光分布式能源和冷热电负荷功率的波动性。以各微网中可控微源出力、可调度电负荷以及微网间的热电交互功率和交互电价为优化变量,建立目标为各微网运行成本最小的纳什议价合作博弈模型。将该非凸优化问题等价变换为两个凸优化子问题,并采用区间序关系和可能度将对应子问题的区间优化模型转化为确定性的凸优化模型。为保证用户的隐私,利用加速的交替方向乘子法对两个子问题进行了分布式求解。最后,通过仿真验证了所提方法的有效性和合理性。

For a class of solvable T-S fuzzy descriptor system with delayed state and saturating input, delay-independent and delay-dependent, stability conditions are correspondingly established using Lyapunov-Krasovskii approach. The stability domain may be enlarged by applying a fuzzy anti-windup compensator to the considered system, and the problem of solving stability domain can be cast into the convex optimization problem.

Compared with traditional robots, flexible robots have higher degrees of freedom and greater flexibility. As one of the sources of inspiration for flexible robots, octopus has very flexible arms, so the imitating octopus arm robot has become the focus of people’s research. In order to analyze the operation of octopus arm, it is very important to establish its model ahead of time. However, the inherent high degree of freedom, underactuation and nonlinearity of octopus arm lead to very difficult modeling of bionic flexible arm. Therefore, according to the physiological structure of the octopus arm, put forward a method of flexible arm geometric segmentation modeling, we use SolidWorks to set up a flexible arm of the physical model, and then import it into Matlab are analyzed, the simulation results show that the flexible manipulator system is established and effective.
