But a relaxed version of continuity can be provided with the help of continuity in discrete sets. In this paper, a definition of higher order sliding mode in discrete-time systems using the concept of relaxed version of continuity in discrete-sets, (p,q)-continuity, is proposed. Moreover, a generalized relationship between sliding order and (p,q)-continuity is defined as the order of the continuity. These definitions facilitates to define ideal sliding and real sliding in arbitrary order discrete-time sliding mode based on (p,q)-continuity concept. Finally, for validation of definitions introduced in this paper, some existing first-order and second-order discrete-time sliding mode control algorithms are used.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121542606","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 this study, second order single-input non-autonomous dynamic open-loop systems will be considered and a higher order polynomial will be used to define the time-varying structure of the angular information. Then, it will be shown via simulations that different phase plane trajectories could be obtained with the proposed method. For the simulations, the trajectory tracking problem will be considered. Then, the same phase plane characteristics obtained using a continuously time-varying linear sliding surface design method selected from the literature will be directly obtained by assigning the polynomial coefficients of the angular sliding surface.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121873485","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}

Hence, it is essential for the developed control approach to be capable of overcoming these unfavorable factors. In the present paper, we consider the problem of controlling underactuated inertia wheel pendulum systems in the presence of parametrical uncertainties and external disturbances. To this end, we present a novel robust sliding mode control (SMC) law without linearizing the original dynamics. More precisely, the system dynamics are first transformed, via several coordinate changes, into a quasi-chained form. Based on this, we construct a new sliding manifold, on which the state variables vanish asymptotically towards the equilibrium point. Then, a nonlinear controller is presented to keep the system state always staying on the fabricated sliding manifold. Lyapunov-based analysis, without performing any linearizations/approximations to the nonlinear dynamics, is provided to demonstrate that the equilibrium point of the closed-loop system is asymptotically stable. We include a series of numerical simulation results to examine its superior performance and strong robustness against uncertainties and extraneous disturbances.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"383 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133480774","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 aim of this study is to find robust controller for demonstrating the availability of the proposed controller, and to achieve best desired output. Here, we have chosen SMC as one of the most effective control methodologies for adjusting the states of the system to their preferred values to supply the excellent damping under severe disturbances. The problem of SMC-FOPID design is transformed to an optimization problem based on performance index, which is Integral of the Time Weighted Absolute Error (ITAE). Where, BA has been employed to adjust the optimal controller parameters. The effectiveness of SMC-FOPID has been tested on a Single Machine Infinite Bus (SMIB) power system under different cases, including operating. The performance of SMC-FOPID controller in power system is compared with a conventional PSS. The simulation results greatly indicate the validity and effectiveness of the proposed controller, and superior robust performance for improvement power system stability compared with the PSS controller for each case.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121283996","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}
