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...
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...
