“…Suppose that the derivative of the disturbances affecting the subsystem is globally bounded, and according to [18], we select the positive parameters. Then, the modified supertwisting with the new nonlinear SMC yields finite time convergence of the sliding surface s i = 0, and the tracking error e i and its derivative _ e i will converge to zero [18,[23][24][25][26][27].…”

This paper deals with the design of a novel modified supertwisting fast nonlinear sliding mode controller (MSTFNSMC) to stabilize a quadrotor system under time-varying disturbances. The suggested control strategy is based on a modified supertwisting controller with a fast nonlinear sliding surface to improve the tracking performance. The paper suggests a simple optimization tool built-in MATLAB/Simulink to tune the proposed controller parameters. Fast convergence of state variables is established by using a nonlinear sliding surface for rotational and translational subsystems. The modified supertwisting controller is developed to suppress the effect of chattering, reject disturbances, and ensure robustness against external disturbance effect. The stability of the proposed controller (MSTFNSMC) is proved using the Lyapunov theory. The performance of the proposed MSTFNSMC approach is compared with the supertwisting sliding mode controller (STSMC) by numerical simulations to verify its effectiveness.

“…Therefore, having a strategy is necessary to overcome these issues, and have reliable trajectory tracking such as super-twisting sliding mode controller (STSMC). STSMC is designed to improve the performance of the controller, and dealing with the chattering phenomena for a RSR [21], underwater robot [22], MEMS gyroscope [23], biotechnological process [24], robot manipulators [25], and industrial electromechanical emulator [26]. To obviate above-mentioned problems, STSMC strategy is utilized in this paper as well.…”

The unmodeled parameters, uncertainties, chattering, and disturbances can be serious problems for a controller. These issues decrease the performance of the controller and make it difficult to have a satisfactory movement path as well. This paper presents a novel hybrid super‐twisting fractional‐order terminal sliding mode controller (HSTFOTSMC) for a rolling spherical robot (RSR) considering bounded model uncertainties for robot dynamics in presence of external disturbances and noise. The controller is based on a new adaptive fractional‐order terminal sliding surface. The stability of the proposed controller is proved by the Lyapunov theory, and then, it is tuned by a novel extended grey wolf optimizing (EGWO) algorithm to adjust the controller parameters, and assure to achieve the precise robot performance. The results of the optimized controller (EGWO‐HSTFOTSMC) are compared with the typical sliding mode controller (SMC), fractional‐order terminal sliding mode controller (FOTSMC), and super‐twisting fractional‐order terminal sliding mode controller (STFOTSMC), which demonstrate the effectiveness of the controller scheme. The controller implementation can potently eliminate the impacts of disturbances, noise, and uncertainties; meanwhile, it decreases the tracking error and increases the convergence speed of robot responses.

“…Ressalta-se que o fenômeno chattering pode causar instabilidade no sistema de controle e problemas com interferência eletromagnética [14]. Uma alternativa para atenuação do chattering é a utilização de controladores Sliding Mode de ordem superior, como o Super-Twisting, utilizado em [13], [15]- [16], que mantém um bom desempenho de regulação e provê significativa atenuação dessas oscilações persistentes.…”

Neste artigo é apresentada uma nova estrutura de controle robusta adaptativa, resultante da união de um Controlador Robusto Adaptativo por Modelo de Referência e um Controlador Adaptativo Super-Twisting Sliding Mode, totalmente desenvolvida em tempo discreto. A estrutura resultante é aplicada em um inversor alimentado em tensão trifásico, conectado à rede elétrica através de um filtro LCL em um ambiente de rede fraca, ou seja, que apresenta significativo teor de indutância. A principal contribuição dessa nova proposta de controle é sua alta capacidade de adaptabilidade, mantendo as características de robustez dos controladores que o compõe. Assim, sua implementação é simplificada, pois pode ser projetado considerando um modelo de referência de primeira ordem e aplicado ao controle das correntes injetadas na rede. Para tal, negligencia-se a dinâmica dos capacitores do filtro LCL durante a modelagem da planta, considerando-a como uma dinâmica do tipo aditiva. Ainda, é apresentada uma análise de estabilidade e robustez do controlador proposto, em tempo discreto, considerando a planta como um todo, isto é, em presença de dinâmicas não modeladas. Além disso, para validar a viabilidade da estrutura de controle proposta, resultados experimentais são apresentados, onde se pode observar que a estrutura de controle proposta é capaz de regular a planta adequadamente mesmo em um ambiente de rede fraca, apresentando bom desempenho, com taxa de distorção harmônica de 2,81%.
