Sliding Mode Stabilization of a Centrifugal Compress or with Spool Dynamics
Chau-Chung Song,Song-Shyong Chen,Der-Cherng Liaw 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
In this paper, the topic of robust stabilization of a centrifugal compress or with spool dynamics is studied and presented. Sliding mode controls for systems with matching-type and mismatching-type uncertainties are seperately designed and verified. The sliding mode design is chosen to achieve the stability of the working equili brium for systems without uncertainties. However, it is known that uncertainties in the spool dynamics and the compress or characteristic are most likely to happen in the real applications. By actuating only the throttle as the single control input, the robust stabilization of the working equili brium is proposed by using as liding mode control. Numerical simulations are given to demonstrate the feasibility of the proposed and derived approaches.

In this paper, the networking architectures and information middleware of wireless sensor networks are developed to construct the heterogeneous information system platform for the real-time structural health monitoring application. The design and implementation of sensor firmware and networking middleware are the key study topics for WSN-based intelligent system platform. The networking gateway of system platform must be developed the independent and highly interoperability to integrate the heterogeneous networks. The application study combined with vibration sensing and GPS positioning is used to demonstrate the feasibility of the developed system platform. The middleware technology is implemented to filter and pre-process the received data from the Zigbee sensor node and extract the available information to transfer to and record in the system database. Moreover, the GPRS and GSM modules are used to be responsible for the long-distance and alarm message transmission on the information network, respectively. Furthermore, the integration system platform is constructed by integrating Zigbee sensor network, GPRS/GSM communication and LAN internet to illustrate and evaluate the feasibility and performance of the proposed architecture for wireless sensor systems. In conclusion, the intelligent system platform of WSN-based monitoring system is developed and integrated to demonstrate and speed up the practical applications of wireless sensor networks in this paper.
Development of a Fuzzy-Q Control for Achieving Robust Inverter Systems
Yu-Kai Chen,Chau-Chung Song 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
This paper presents a fuzzy control including the nonlinear effects of the output-filter inductor. Since the filter inductance will drop dramatically when the inverter system is operated at heavy loads, system dynamic performance will vary over a wide range. In the system, a linear relationship between quality factor Q and resonant peak Mr of theoutput filter can be derived. Therefore, Q-parameter is selected as an input variable of the fuzzy-Q control to improve the system performance by modifying the fuzzy rule. The inverter systems with the fuzzy-Q control scheme can compensate the influence due to variations of filter inductance and loads. Thus, a robust inverter system can be achievedwith the proposed fuzzy-Q control.
