This mode of operation, constant cutting velocity combined with different profiles of materials to be cut, causes variable cutting forces to be applied to the saw. As a result, the cutting off machine is generally set for the worst expected conditions, otherwise excessive wear of the saw and machine will occur. Further, traditional cutting-off machines require adjustments to be made in order to automatically detect the completion of a cut. The objective of this project is the study of the application of control algorithms to the process of cutting-off metallic pipes or bars, with variable profiles, implemented in an industrial cutting-off machine, commercially available. The testes algorithms concern real-time cutting control and automatic detection of cut completion. The algorithms are implemented in a low cost programmable logic controller (PLC), allowing its adoption in industrial applications without significant increase on machine cost. All algorithms were developed having in mind safety issues relative to the operation of the cutting machine in order to prevent damage to the machine itself. Also, all process related relevant parameters are monitored on a personal computer using OPC (object linking and embedding-for process control).","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132832898","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}

DC motor drive, with a basic control loops and changeable moment of inertia belongs to the class of the higher order systems with changeable parameters. In a way to preserve the desired system behaviour, even in the case of system parameter change, the simplified MRAC algorithm with parameter adaptation was developed and applied for control of the DC motor drive. The algorithm is based on the classical model reference adaptive control approach with parameter adaptation, including few simplifications. The simplifications are as follows: the reference model and the state vector were reduced to the third order, only output variable was used in the algorithm and the total number of the algorithm coefficients was reduced to seven. The satisfactory behaviour of the adaptive control algorithm was preserved by using differences of the output variable instead of its derivatives. Furthermore, an adaptive control algorithm was normalized for the usage in the whole range of reference signal changing. Adaptive control coefficients were obtained by off line optimization, for the extreme amount of the changeable system parameter. Therefore, the same coefficients could be used in whole range of the system parameter variation. The simplified MRAC algorithm with parameter adaptation was implemented in the dSPACE DS1102 micro controller platform based on microprocessor TMS320C37. This controller is used for control of the DC motor drive with a changeable moment of inertia. Finally, it was evident from the experimental results that the application of the MRAC with the simplified discrete parameter adaptation algorithm significantly decreases the influence of the plant parameter variations and the influence of disturbance to the system behaviour.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115150664","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}

Basically, these types of energy generation are very favourable for the environment but do not produce power on customers load demands, have long intervals of lacking power generation due to absence of power input (no sunshine, no wind), and especially exhibit high costs per installed power respectively per generated energy. So every cost saving and output increasing measure should be taken. Combining a photovoltaic power unit with a wind energy unit will reduce the zero-power intervals and can be composed to high extent of standard commercial variable speed drive elements. These are PWM voltage source inverters with active front end, and also standard induction machines can be taken. Only a few extensions are necessary, thus the total hardware system is rather cost effective. It is essential that a system control unit defines setpoint values for the sub-units and handles abnormal operating conditions. Here a fuzzy control system is proposed to accomplish these tasks. It means performing the standard power insertion into the line on the principle of maximum power tracking, preferable at a rather constant power input without flicker power, ensuring or improving line voltage quality with regard to reactive power and distortion power, or voltage waveform improvement, respectively. In addition, in case of a line interruption, the unit should be able to run independently from the line, establishing an insular power supply for the nearby customers and loads until the reconnection to the mains is done.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131908497","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}

Potential separation is required between the modules and grid. A standard 5 Hz transformer can accomplish this separation. Heavy in weight, loud in noises and exhibiting high temperatures through the transformer make the whole system large in volume and expensive. By discussing optimisation facts, new ideas in the conversion structure have been found in a two-inverter conversion concept and will be evaluated in this synopsis. The main idea of this new concept is to make the necessary separation also with a transformer but with a ferrite core and an operating frequency of 2 kHz. Optimised for these 2 kHz the above-mentioned problematic facts will be minimised. The first converter is used for the DC-AC conversion to the base of 2 kHz. The second inverter, supplied after the transformer and a stabilised rectifying system, makes the DC-AC conversion to the 5 Hz grid. Further on, component costs will be reduced through using the same kind of inverter. Also the control management is more modular and effective.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131930602","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}
