Considering that dynamic model of ACFTCS is a high-order form, in order to analysis conveniently, a first order plus dead-time model of system is acquired by model reducing method. A predictive functional control (PFC) technique is applied to the temperature control of the ACFTCS on the basis of presentation of predictive functional control (PFC) algorithm for first order plus dead-time system. To verify the validity and effectiveness of the developed model and PFC control strategy, simulations and experiments are carried out. Experiment results shown that absolute and relative error are from 0.01to 0.24°C as well as 0.04% to 1.8%respectively when setpoint temperature varying from 5 to 65°C. Simulation results shown that the control strategy is effective and a good control performance is obtained in regard of setpoint tracking, robustness properties, and disturbance rejection.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122310759","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}

The bridge uses one thermistor to detect temperature variation and one adjustable resistor to regulate bridge ratio.

A laser beam profiler based on detector array is developed to measure the far-field beam absolute intensity and temporal-spatial distribution of the high repetition rate pulsed laser beam. In the experiment, the pulse width of laser is about 100ns, the repetition rate is adjustable between 1 kHz and 20 kHz, and the diameter of the far-field beam is about 20cm. The detector array is composed of 297 Si-PIN photodiode detectors with the spatial resolution of 1cm in the central region. The image of the far-field beam profile is reconstructed with the bilinear interpolation method. The beam profiler is capable for measuring far-field beam profile of high repetition rate pulsed laser, with response wavelength between 400nm and 1100nm, minimal detectable pulse width of about 10ns, and dynamic range of energy density of 0.02–100µJ/cm2.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129071636","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}

In order to reduce these noises, we can use hardware to reduce the noise impact, but it will raise the costs or bring inconvenience.

However, the electric characteristics of the transducers vary greatly with temperature, which will cause the deficiency of static matching. The existing tuning method or dynamic matching method may compensate for the variations, but they both have some limitations in applications. In this paper, a method based on the Wien bridge oscillation circuit is proposed to dynamically measure the equivalent static capacitor of ultrasonic piezoelectric transducer. It can overcome the limitations facing the conventional dynamic matching and help to realize self-adjusting of the matching inductors. This method is adaptable for a variety of ultrasonic instruments and devices, especially for the ultrasonic flow meters.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131088211","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}
