Therefore, in this paper, we present an effective control method based on neural network gain-scheduled PD (NNGS-PD) and model reference controller-based PD (MRC-PD) for quadcopter attitude stabilisation and altitude tracking. Both nonlinear and linear methods verified the stability and robustness of the proposed controllers. The simulation results illustrate that the synthesis control methods have good performance in terms of attitude and altitude tracking when faced with external disturbances.","PeriodicalId":249374,"journal":{"name":"International Journal of Nonlinear Dynamics and Control","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124521031","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 the first case electrical current produced by an amplifier is converted by the transducer into mechanical force, which leads to vibrations of the base. A mechanical oscillator is mounted on the transducer base. The influence of oscillator vibrations on the formation of the driving force leads to a number of specific effects, in particular, to the Sommerfeld-Kononenko's effect. Steady-state regimes of the constructed model are investigated by methods of the theory of dynamical systems. Expressions for supplied and consumed powers are shown and investigated for regular and chaotic regimes. The inverse problem model is also discussed. The classical results for wave power absorption by wave energy extractor as a single degree of freedom system are presented in the second considered problem. The example includes an axisymmetric buoy which oscillates and is subjected to its natural hydrostatic restoring force. Main attention focuses on the values and expressions for the mean powers. The expression for the maximum mean power is given for the considering system.","PeriodicalId":249374,"journal":{"name":"International Journal of Nonlinear Dynamics and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128462985","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}

Relative gain array (RGA) was used to determine the level of loop interaction. Dynamic decoupler was used to remove the interactions which were obtained using feed-forward design technique. A feedback control system is designed for the dynamic decoupled plant using Ziegler-Nichols tuned proportional integral (PI) controller. A genetic model reference adaptive controller (GMRAC) is designed to control the fractionator using a second order reference model and adaptation mechanism based on genetic algorithm (GA). Genetic algorithm uses real-coded data generation for optimisation. Comparison is made with the PI controller.

Photovoltaic systems have one of the highest potentials for generating electrical power. In this system, the photovoltaic cell is the basic device of the conversion process. Indeed, photovoltaic cells are low power generators. Therefore, association of serial and parallel cells and modules forming photovoltaic generator is mostly recommended for supplying isolated areas where pumping systems play a predominant role. However, the generated power depends, essentially on temperature and solar irradiation. So, to improve photovoltaic installations yield, a maximum power point tracker controller serves to maximise produced power whatever climatic operating conditions. Furthermore, due to remarkable performances, researches proved that pumping systems-based photovoltaic generators became ideal structures for remote areas. The simulation results under MATLAB/Simulink software reveal that the proposed system is versatile.","PeriodicalId":249374,"journal":{"name":"International Journal of Nonlinear Dynamics and Control","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128401069","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}
