Micro/nano positioning technologies have been attractive for decades in industrial and scientific applications fields. The actuators have inherent hysteresis that can cause system unexpected behave in some extend. In this research, the authors used extented unparallel Prandtl-Ishlinshii(EUPI)models to represent the input-output relationship of a piezo-driven micro position stage. Integral inverse(I-I) compensator is used for compensating the hysteresis characteristics of the micro positioning stage and compared with direct inverse(D-I) compensator and inverse model(I-M) compensator. However,the accuracy and the robustness of the I-I compensator are worse when there is noisy in the system,a novel sliding-mode-like-control with EUPI(SMLC-EUPI) method was proposed and analyzed by different trajectory tracking experiments in Matlab environment. Though the above strategies can alleviate most deviation, the adjustment of the SMLC’s parameters is very complex. So the fuzzy method is used to adjust these parameters and be verified by trajectory tracking experiments. Finally,for validating the proposed control method, the paper did the corresponding experiment in microscope with CMOS and obtained convincing results.

Characteristic Analysis of Hybrid Stochastic Timed Petri Net

一种大工作空间密度的压电微动二维工作台设计

第30届中国控制与决策会议

作者： ruimin cao Lina Hao Guoli Bai Qiang Gao School of Mechanical Engineering & Automation Northeastern University Key Laboratory of Manufacturing Industrial Integrated Automation Shenyang University

In this paper, an interesting Hybrid Stochastic Timed Petri Net（HSTPN） is introduced synthetically for a class of hybrid systems with discrete, continuous, conflicting, time-delay and stochastic characteristics simultaneously. Each tuple of the model is performed in detail, the dynamic performance and reachability are analyzed. The proposed HSTPN outperforms conventional hybrid Petri net models in terms of describing the scalability and description capability to hybrid characteristics of hybrid systems. Taking the automatic sorting hybrid system as an example, through analyzing the complexity in modeling, we show how the HSTPN could be adopted to the automatic sorting hybrid system and finally the rationality and effectiveness of HSTPN model are verified.

关键词： Hybrid Stochastic Timed Petri Net Hybrid dynamic system Hybrid states Automatic Sorting System

微山湖是由赤山、微山、吕孟、张庄、武家、黄山等诸小湖汇集而成的。武家湖在留城南、黄山湖在黄山东,其它四个小湖皆在今微山岛附近。诸小湖出现的时间,当在明弘治至嘉靖四十四年间。其理由是:《漕河图志》在记述沿漕河的湖泊时,未有提到诸小湖,到嘉靖四十五年(1566年),朱衡主持开凿漕运新渠时,诸小湖皆出现了。隆庆三年(1569年)徐阶撰《漕运新渠记》说:“……又溯薛河之上流,凿王家口,导其水入于赤山湖;凿薛城之左右,导玉花泉、赶牛沟之水……经微山、吕孟诸湖,达于徐。”万历《兖州府志·山水》:“微山在(滕县)城南一百里,……其下为微山湖,黄沟水入焉,又东南(应为东北——笔者)为赤山,其下为赤山湖,又稍南为吕孟山,其东南为吕孟湖。”这不仅告诉我们诸小湖的位置,而且说明它们是各自为湖的。
