The novelty of the proposed approach is that the sliding mode switching functions are chosen in such a way that the multivariable coupled system is controlled as a whole. Hence, no need to divide the system model developed in the synchronous dasiadqpsila reference frame into two separate loops. Furthermore, the proposed control strategy allows a better stability and robustness over a wide range of operation. When sine PWM is used for generation of pulses for the switches, a variable switching nature is exhibited. The pulses for the active filter are fed by a Space Vector Modulation in order to have a constant switching of converter switches. But, the conventional space vector modulation, if implemented practically, needs a complicated algorithm which uses the trigonometric functions such as arctan, sine and cosine functions which in turn needs look up tables to store the pre-calculated trigonometric values. In this paper, a very simplified algorithm is proposed for generating Space vector modulated pulse for all six switches without the use of look up tables and only by sensing the voltages and currents of the voltage source inverter acting as shunt active filter. The simulation using PSIM software verifies the results very well.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126409330","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 discrete time model of the system is derived. The stability region in the parameter space is obtained for different values of reactive current. The analysis is done for type II controller where the parameters are the proportional and integral gains. It is found that increase in integral gain results in period doubling bifurcation and increase in proportional gain results in border collision bifurcation.

The hardware implementation of the open-loop control using IC MC 33035 is described. In addition to the conventional PI controller, intelligent controllers based on fuzzy, neuro and neuro-fuzzy techniques have been designed using the d-q model of the PMBLDC motor.

Implementation issues include limited on-chip program memory, unsigned integer arithmetic, and computational delay. The duty cycle for the dc-dc converter can only be updated every eight switching cycles because of the time required for the A/D conversion and the control calculations. However, it is demonstrated here that stable responses can be obtained for both buck and boost converters under these conditions. Another important result is that the same microcontroller code, without any modifications, can control both converters because their behavior can be described by the same set of linguistic rules.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125308390","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}
