“…Traditional sliding mode control, as a nonlinear control method with strong robustness when dealing with system time-varying, nonlinear, and uncertainties, is widely used in motor servo control systems [9], power control systems [10], and electro hydrostatic actuators [11]. However, traditional sliding mode control compensates for uncertainty by using the high gain in the discontinuous control law.…”

The electromagnetic linear actuator is used as the core drive unit to achieve high precision and high response in the direct-drive actuation system. In order to improve the response performance and control accuracy of the linear drive unit, an improved sliding mode-active disturbance rejection control (ISM-ADRC) method was proposed. A motor model was established based on improved LuGre dynamic friction. The position loop adopts the improved integral traditional sliding mode control based on an extended state observer, and the current loop adopts PI control. The stability of the system is verified based on the Lyapunov theory. A nonlinear dilated state observer is used to effectively observe the electromagnetic linear actuator position and velocity information while estimating and compensating the internal and external uncertainty perturbations. At the same time, the saturation function sat(s) is used to replace the sign(s) and introduce the power function of the displacement error variable. The improved integral sliding mode control law further improves the response speed and control accuracy of the controller while reducing the jitter inherent in the conventional sliding mode. Simulation and experimental data show that the proposed improved sliding mode-active disturbance rejection control reduces the 8-mm step response time of the electromagnetic linear actuator by 21.9% and the steady-state error by less than 0.01 mm compared with the conventional sliding-mode control, while the system has 49.4% less adjustment time for abrupt load changes and is more robust to different loads and noise.

“…However, the current inner loop of the BDFIM has a complex nonlinear structure and is easily interfered by various disturbances. Since Slide Mode Control (SMC) has the advantages of easy decoupling, disturbance rejection, insensitive to parameter variations, this method is often applied to control AC drives [13]. However, due to the inherent characteristics of SMC, it does not include solutions with constraints.…”

This paper proposes a cascade proportional-integral continuous second-order sliding mode control method for brushless doubly-fed induction machine. This method consisting of speed out-loop Proportional-Integral controller and current inner-loop sliding mode controller. The PI controller provides reference to the inner-loop sliding mode controller with constraints according to the system requirements in terms of maximum current and speed limits. The sliding mode control method is designed to achieve excellent robustness and anti-interference ability, which is suitable for machines with nonlinear structures. Experimental results demonstrate the fast dynamic performance and excellent robust tracking of the proposed method.

“…This paper proposes a robust intelligent SMC with a simple architecture and a clear design methodology for MPPT-based high-performance pure sine wave inverters. The robust SMC using nonlinear regime not only ensures that the system state can reach the sliding surface in a limited time, but also demonstrates the capability to suppress severe intrusions in a closed-loop feedback system, which can allow the control more accurate and ensure the stability of the system [17][18][19][20]. The steady-state performance and tracking speed during transients in MPPT inverter system can be improved indeed [21][22][23].…”

Photovoltaic (PV) power generation has been extensively used as a result of the limited petrochemical resources and the rise of environmental awareness. Nevertheless, PV arrays have a widespread range of voltage changes in a variety of solar radiation, load, and temperature circumstances, so a maximum power point tracking (MPPT) method must be applied to get maximum power from PV systems. Sliding mode control (SMC) is effectively used in PV power generation due to its robustness, design simplicity, and superior interference suppression. When the PV array is subject to large parameter changes/highly uncertain conditions, the SMC leads to degraded steady-state performance, poor transient tracking speed, and unwanted flutter. Therefore, this paper proposes a robust intelligent sliding mode MPPT-based high-performance pure sine wave inverter for PV applications. The robust SMC is designed through fast sliding regime, which provides fixed time convergence and a non-singularity that allows better response in steady-state and transience. To avoid the flutter caused by system unmodeled dynamics, an enhanced cuckoo optimization algorithm (ECOA) with automatically adjustable step factor and detection probability is used to search control parameters of the robust sliding mode, thus finding global optimal solutions. The coalescence of both robust SMC and ECOA can control the converter to obtain MPPT with faster convergence rate and without untimely trapping at local optimal solutions. Then the pure sine wave inverter with robust intelligent sliding mode MPPT of the PV system delivers a high-quality and stable sinusoidal wave voltage to the load. The efficacy of the proposed method is validated on a MPPT pure sine wave inverter system by using numerical simulations and experiments. The results show that the output of the proposed PV system can improve steady-state performance and transient tracking speed.
