One of the safety issues for autonomous car is the car inability to faithfully track a pre-planned path, which might cause the car deviate from its intended course. This could lead the car to crash or involve in accident. To address this issue, this paper proposes a path tracking method based on Proportional and Proportional-Derivative controllers considering the kinematic constraints of the car. The performance of both controllers for car-like robot path tracking is evaluated and analysed. The proposed method has been proven to minimize the tracking errors which could help to enhance the safety level of the car.","PeriodicalId":6540,"journal":{"name":"2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE)","volume":"77 1","pages":"223-227"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86185759","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 method complements the vast research within autonomy to achieve the most fuel efficient solution from results that are already available from concept evaluation and system optimization in early development. The optimal control results are validated and compared to an extensive empirical study to ensure realization in real applications. The optimal control method is based on dynamic programming and finds the global optimum in regards to fuel efficiency [ton/l] at a given productivity [ton/h]. The wheel loader is used as an example due to the complex nature of the system, where the driveline and working hydraulics must work together throughout the work cycle. The main focus in this paper is how to transfer results from the optimal control calculations done offline, with high computational power, to algorithms that can be used online in operator assist systems, automatic functions and autonomous machine control. The primary result is that the method and algorithms presented in this paper works. The secondary results is that the optimal control solution shows around 15% higher fuel efficiency compared to the highest fuel efficiency measured among real operators in the extensive empirical measurement. The operator with the highest measured fuel efficiency has 20–30% higher average fuel efficiency than the fleet implying that the optimal control results, if used in operator assist systems, automatic functions and autonomous machine control, can increase the average fleet fuel efficiency by up to 35–45%, depending on operator and application.","PeriodicalId":6540,"journal":{"name":"2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE)","volume":"82 1","pages":"113-118"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76133194","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}

To overcome this limitation, this manuscript presents a modified Smith delay compensator based PCCS. Stable, integrating and unstable processes with dead time are considered in this work. The proposed PCCS consists of a secondary disturbance rejection controller, a stabilizing controller, a setpoint tracking controller, a setpoint filter and a lag filter for the predicted disturbance. Settings of the primary setpoint filter and setpoint tracking controller are obtained using direct synthesis approach whereas the secondary disturbance rejection controller is designed using internal model control approach. Routh-Hurwitz stability criterion is used to design the stabilizing controller. Moreover, the method of choosing primary and secondary closed-loop time constants is discussed. Simulation studies show that the proposed scheme results in enhanced regulatory performance which is very much essential in process industries.","PeriodicalId":6540,"journal":{"name":"2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE)","volume":"293 1","pages":"234-239"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80031112","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}

PLC being a new wired protocol is still under development to communicate with other protocols including wireless protocol for seamless connection. The study focuses on interconnecting ZigBee wireless protocol to the said wired protocol by developing a gateway to convert their protocols into one common protocol. A method used in converting protocols includes varying the PLC's Programmable System on Chip (PSoC) into a computer architecture which enables Universal Asynchronous Receiver/Transmitted (UART) communication to successfully interconnect with ZigBee. The said interconnection is applied on a fuzzy logic controlled light system in which transmission test and power consumption was evaluated.

This research proposed a method to extract multiword expression candidates from texts in a corpus. The text is tokenized and then filtered with stop words to remove unnecessary words. The result of these steps is multiword expression candidates that are still mixed with common and uncommon multiword expressions. To filter uncommon multiword expressions, they are ranked with the other multiword expressions from the other texts within the same corpus by using TF-IDF algorithm. This research evaluates three options for extracting multiword expression candidates. The option which utilizes combination of special characters and stop words to determine word combination is promising because it excels in combining word rate, has more appropriate multiword expression candidates, while it spends almost the same amount of memory usage compared to the others.","PeriodicalId":6540,"journal":{"name":"2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE)","volume":"89 1","pages":"304-309"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81481536","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}
