When designing the interactive controller with a more realistic consideration, connectivity needs to be maintained instead of simply assumed. In this paper, we give an introduction on how to maintain the connectivity of a communication graph which corresponds to a WRN. Due to the limited communication range of robots, proximity-limited communication models are used for the co-operative control problem and the connectivity maintenance problem in WRNs. Therefore, we review two kinds of proximity-limited communication models in this paper: the disk-based communication model and the hysteresis-based communication model. In addition, we present some network performance optimization work that based on communication metrics of Bit Error Rate (BER) and Signal to Interference plus Noise Ratio (SINR). Finally, we propose a new framework that involves the connectivity control and the network performance optimization, and potential solutions are discussed accordingly.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125016586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photovoltaic (PV) generation of electricity is an important renewable energy source, especially at small scale, such as in homes. To increase the value of small-scale renewable generators, one efficient way is to aggregate and control their output and group them in zones. One challenge of doing this is the precise forecasting of each PV output. This paper introduces our developed irradiance forecasting algorithm based on the data from a sky camera. A SVM regression technique is used to generate regress curves between future irradiance and other available information.

Cyber-Physical Systems (CPSs) can offer numerous opportunities to design high efficient control systems. In this paper, we focus on the design of temperature control systems. By using the idea of CPS, a hybrid temperature control (HTC) system is proposed. It combines supervisory and proportional-integral-derivative (PID) controllers. Through an energy efficient temperature control (EETC) algorithm, HTC system enables to monitor and maintain the room temperature in the desired interval with three actuators: air-conditioner, window and curtain. As the tight integration of physical and cyber worlds, the sensing accuracy of physical platform has significant impact on the performance of HTC system. Through simulations and field experiments, the relationship between control performance and sensing accuracy is captured. A fitting function method is proposed to improve the sensing accuracy without increasing monetary cost of the system implementation. By using this method, the performance of HTC system can be increased obviously.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121275286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper uses the improved fuel economy as the main target, the characteristic parameters of system in the future are predicted, and the speed and torque of the motor are adjusted with respect to the predictive results. An on-line optimization approach is applied to the real-time control, and the typical driving cycle is simulated by Matlab/Simulink.

Unlike conventional ROV driving systems, which only transmit commands from the pilots to the vehicle controller, the proposed haptic device has the ability to provide information about the working environment back to the operator via tactile sensing. In this paper, the drag force generated by the fluid interaction is chosen as the feedback objective for the haptic control. Hence, the haptic device helps the operator to sense the drag force via feedback through the joystick. A one degree of freedom (1-DOF) haptic joystick was developed to first control the surge motion of a simulated ROV model, with future work aimed at evaluation on an actual vehicle. The results of the haptic controller linked to the simulation model proved the feedback ability of the controller and identified areas of improvement, especially with regard to noise filtering.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129883125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
