It will be shown that the transfer function,G(z) obtained via the step invariant design method, may be made to approximate closely to the transfer function, G(z) obtained via the bilinear z-transform method. The analysis presented justifies this step-invariant design method, and shows that it is possible to convert a time domain (step-invariant) filter, G(z) to one that satisfies a frequency domain specification,G(z) . This is achieved by observing certain conditions and by employing a suitable gain term. The validity of the method is demonstrated using a practical example of a simple highpass filter and a digital phase-advance network.","PeriodicalId":290911,"journal":{"name":"IEE control engineering series","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128434383","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}

These will be demonstrated with reference to a RTKBS approach for the improved supervision and control of fermentation plant. The system is composed of three elements; a supervisory knowledge base, a scheduling knowledge base and an on-line relational database. The supervisor is responsible for monitoring and controlling individual fermenters and is instructed when to initiate or terminate a fermentation by commands issued by the scheduler, which aims to maximise plant-wide productivity. The system also performs sensor validation, fault detection/ fault diagnosis and incorporates relevant expertise and experience drawn from both the process engineering domain and the control engineering domain. The database provides a centralised store of information which can be retrieved on line by both knowledge bases.","PeriodicalId":290911,"journal":{"name":"IEE control engineering series","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699719","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}

A control scheme to drive the state into the sliding mode has been outlined, along with a method of reducing the chattering component of the control.

A fundamental aspect of artificial neural networks is the use of simple processing elements which are essentially models of neurons in the brain. These elements are then connected together in a well-structured fashion, although the strength and nature of each of the connecting links dictates the overall operational characteristics for the total network.","PeriodicalId":290911,"journal":{"name":"IEE control engineering series","volume":"299302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116580064","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}
