In this paper, we have exploited the first-order sliding mode control method to track the ECG data of the human heart by three different nonlinear control laws. In order to lessen the intrinsic chattering of the classic sliding mode control system, smooth function approximations of the control input, by means of the hyperbolic tangent and the saturation function, were used. The fast Fourier tra...

An adaptive sliding mode control (SMC) based on fuzzy logic and low pass filter is designed in this research. The SMC one of the most widely accepted robust techniques. However, main disadvantage chattering phenomena, which inhibits its usage many practical applications. Fuzzy has supplanted conventional techniques A major feature ability to express amount ambiguity individual perception human ...

Abstract An optimized sliding‐mode observer control algorithm for permanent magnet synchronous motor (PMSM) is proposed to solve the problems in conventional algorithms (e.g., system chattering and phase delay). The adopts a new piecewise function as switching reduce chattering. low pass filter substituted with complex coefficient delay caused by filter. Moreover, counter emf back obtained usin...

Due to the quadrotor’s underactuated nature, suspended payload dynamics, parametric uncertainties, and external disturbances, designing a controller for tracking desired trajectories quadrotor that carries is challenging task. Furthermore, one of most significant disadvantages nonlinear systems infinite-time convergence trajectory. In this paper, finite-time neuro-sliding mode (FTNSMC) with sub...
