The proposed estimator includes: 1) a new PLL algorithm preceded by a smooth variable structure filter (SVSF) to synchronize grid voltage signal and minimize the noise influence of the grid voltage signal and 2) a fast upper-triangular and diagonal recursive least square (FUDRLS)-based active and reactive power estimation algorithm using instantaneous power signal and estimated phase angle from the proposed PLL. The proposed method provides more accurate and faster active and reactive power estimation than conventional recursive least square (RLS)-based and discrete Fourier transform (DFT)-based methods. Moreover, the proposed estimator is relatively insensitive to noise since the SVSF is inherently robust to noise and to modeling uncertainties. Due to its low computational complexity and numerical stability, the proposed method is suitable for the real-time embedded system to estimate active and reactive power and for an alternative PLL method for control applications of the grid-connected converters.","PeriodicalId":220324,"journal":{"name":"2018 IEEE 3rd International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114993511","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}

By Changing the exit angle of the incident laser, the three-dimensional information of a space object can be received. This paper researches on the response problem of one kind of 2D electromagnetically driven micro-mirror by numerical analysis and finite element analysis method. The aim of response analysis is to obtain the angle matching of biaxial deflection under a certain proportional driving force. The dynamic model of the mirror was established firstly. Then, a numerical method called Newmark- $beta$ method was used to design optimized structure and simulate time domain response of the mirror. The ratio of slow to fast axis angle is 5.156:1 when taking the damping factor into account. The finite element analysis was carried out to further verify the results of the response analysis. By frequency domain response experiment, the ratio of slow and fast angle was 5.04:1, which confirmed the angle matching relationship of slow and fast axis near resonant frequency.","PeriodicalId":220324,"journal":{"name":"2018 IEEE 3rd International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"44 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113969823","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}

As an important performance metric, Memory Level Parallelism (MLP) describes how many cache misses can be serviced concurrently. Prior studies on MLP modeling are either based on mechanistic analyses without considering the cache miss behavior or empirical fittings with bare insights. According to our experimental results, however, we find that MLP is highly dependent on the cache miss patterns. Based on this observation, this paper proposes an analytical model which estimates MLP more accurately and efficiently. Similar to previous approaches, the input of our model is the statistical information of executed software that can be profiled easily from the memory traces. Eleven benchmarks from Mobybench suite are chosen to evaluate the model with different cache sizes. Comparing to the results from gem5 cycle-accurate simulations, the mean absolute error of our model is around 3.4%, which is significantly lower than Jian Chen's 18% and Qin Wang's 7%. Additionally, our model can bring 35 times speed up relative to cycle-accurate simulations, which is similar to the time overhead of Jian Chen's and Qin Wang's models.","PeriodicalId":220324,"journal":{"name":"2018 IEEE 3rd International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134296034","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 proposed PWM/PFM control technique used multiplexers combines PWM modulator and PFM modulator together to simplify the circuit. There are two parallel paths to realize the transition from PFM mode to PWM mode for improving transient response. The first path dominates mode transition when the load current changes from light to 120mA-260mA, the second path dominates mode transition when the load current changes from light to 260mA-1A. Simulation results demonstrate that the proposed PWM/PFM control technique can realize auto-mode transition between PWM mode and PFM mode. The undershoot voltage is 75.8mV and recovery time is $3.3mutext{s}$ when the load current changes instantaneously from 10mA to 1A. Meanwhile, above 80% conversion efficiency can be reached over a load current range of 10mA-1A.","PeriodicalId":220324,"journal":{"name":"2018 IEEE 3rd International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133484764","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}
