Its main advantage is the ability to optimize a quadratic cost function on a very long horizon (potentially infinite). In its basic form, it requires linear system which is not the case in many AC drive control problem. However, various approximations, such as gain scheduling or state dependent Riccatti Equation (SDRE) approach, were proposed and applied to this task. They have certain advantages, however, they all still suffer from the essential problem of LQ approaches, namely its inability to respect hard constraints on the system state variable. In this paper, we interpret the LQ controller as an approximate solution of the constrained problem and use the limited lookahead approach of approximate dynamic programming to introduce the constraint on the amplitude of the drive currents. This yields a constrained quadratic optimization problem, for which we design an iterative solution. Performance of the algorithm is tested in simulation and experimentally on a laboratory prototype of a 10.7 kW PMSM drive.","PeriodicalId":271130,"journal":{"name":"2015 IEEE International Symposium on Predictive Control of Electrical Drives and Power Electronics (PRECEDE)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133516843","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}

Estimation of the rotor position is based on the standard injections of high frequency signal into the voltage command for a PWM. It is intended to achieve the same effect using the FCS-MPC. The FCS-MPC usually operates with a short sampling period, therefore the estimation algorithm needs to be computationally cheap. Moreover, the cost function needs to be modified to secure injection of high frequency (hf) voltage signals into a given axis in a reference frame linked with the rotor position. In this paper, a method of injection of a harmonic signal using FCS-MPC is proposed, using an extension of the cost function. Rotor position and speed estimation is based on the conventional phase-locked loop. Theoretical assumptions are verified by both simulations and experiments on a laboratory prototype of PMSM drive with rated power of 250 W.","PeriodicalId":271130,"journal":{"name":"2015 IEEE International Symposium on Predictive Control of Electrical Drives and Power Electronics (PRECEDE)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123244719","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}

Due to increasing calculation power of state-of-the-art control hardware platforms and computationally efficient MPC approaches, MPC is already feasible for processes with small time constants as they are common in converter and drive control. In this paper, a 27-to-3-phase thyristor matrix converter (also known as cycloconverter) is considered. Such a converter can be controlled with the standard control angle approach. However the full available system performance cannot be utilized using this standard method, since each of the grid phases is separately controlled. Compared to the standard method, the MPC as a multi-variable control algorithm considers the whole coupled overall system. Due to this, all 273 = 19683 switching states are considered. Besides the proof of the function of a Direct MPC for the 27-to-3-phase thyristor matrix converter, this paper also demonstrates that the commutation frequency can be distinctly reduced by the use of the MPC. Since the switching losses mainly depend on the switching frequency, the converter losses will be significantly reduced by this method.","PeriodicalId":271130,"journal":{"name":"2015 IEEE International Symposium on Predictive Control of Electrical Drives and Power Electronics (PRECEDE)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123297751","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}
