“…Other works use SMC theory to propose complex controllers to track i r by generating the duty cycle of the Boost converter [14,[23][24][25]. In [23], the authors propose an SMC observer for i L and v dc , and combine this observer with a triangular signal to generate a PWM with a fixed frequency.…”

“…Moreover, the works presented in [14,24,25] use complex switching functions to implement the SMCs. In [14,24], the proposed switching functions include the inductor current error as well as its first [14] and the second integrals [24]; while in [25], the switching function considers the inductor current and output voltage errors along with their integrals. On the one hand, the advantages of the work introduced in [14] are: it combines two switching functions to provide robustness to uncertainties in the inductor resistance and inductance; it performs a Lyapunov-based stability analysis; and the controller includes a PI to regulate v dc and to provide zero steady-state error.…”

“…However, one of the switching functions is not clearly defined and there is no design procedure for the PI parameters. On the other hand, the advantages of the work presented in [24] are: it provides a design procedure for the SMC parameters (based on frequency response); it performs the stability analysis using sliding-mode theory; and the SMC is implemented with a commercial PFC controller (integrated circuit). However, the controller does not include an outer loop to regulate v dc (i.e., v dc has a steady-state error), the SMC implementation with the commercial PFC integrated circuit is not clearly justified, and the experimental results show high ripples in i L .…”

Rectifiers with power factor correction are key devices to supply DC loads from AC sources, guaranteeing a power factor close to one and low total harmonic distortion. Boost-based power factor correction rectifiers are the most widely used topology and they are formed by a power stage (diode bridge and Boost converter) and a control system. However, there is a relevant control problem, because controllers are designed with linearized models of the converters for a specific operating point; consequently, the required dynamic performance and stability of the whole system for different operating points are not guaranteed. Another weak and common practice is to design the power and control stages independently. This paper proposes a co-design procedure for both the power stage and the control system of a Boost-based PFC rectifier, which is focused on guaranteeing the system’s stability in any operating conditions. Moreover, the design procedure assures a maximum switching frequency and the fulfillment of different design requirements for the output voltage: maximum overshoot and settling time before load disturbances, maximum ripple, and the desired damping ratio. The proposed control has a cascade structure, where the inner loop is a sliding-mode controller (SMC) to track the inductor current reference, and the outer loop is an adaptive PI regulator of the output voltage, which manipulates the amplitude of the inductor current reference. The paper includes the stability analysis of the SMC, the design procedure of the inductor to guarantee the system stability, and the design of the adaptive PI controller parameters and the capacitor to achieve the desired dynamic performance of the output voltage. The proposed rectifier is simulated in PSIM and the results validate the co-design procedures and show that the proposed system is stable for any operating conditions and satisfies the design requirements.

“…In this method, traditional proportional + integral + derivative (PID) controllers are usually used to control the current and voltage loops. PWM rectifiers have a highly non‐linear structure, external and input disturbance uncertainties, and non‐minimum phase characteristic [6, 7]. If PWM rectifier is controlled a conventional PID controller, a mathematical model of the system is required.…”

Diode and thyristor-based rectifier circuits have been widely used in the industry. Due to non-linear structures of these circuits, they draw non-sinusoidal current from AC network as well as cause a low power factor in the AC side. The DC-link voltage of rectifier is affected by the changes in AC network or by the load variations on the DC side. Pulse-width modulated (PWM) rectifiers can eliminate the mentioned power quality problems if they control properly. This study proposes a controller with an adaptive and robust structure based on proportional + derivative type-2 fuzzy neural network (PD-T2FNN) for DC-link voltage control of PWM rectifier. Dynamic performance of PWM rectifier using the proposed controller is evaluated via dSPACE based experimental setup under different operation conditions: set-point change, step load change in the DC side of the rectifier, set-point change under load and capacitive operation mode. The experimental results are given for traditional PD and proportional + integral and T2FNN controllers to validity performance of the proposed controller. Performances of controllers are evaluated regarding settling time, overshoot, steady-state error and total harmonic distortion. PWM rectifier with PD-T2FNN DClink voltage controller has superior performance for all operating conditions according to performance criteria when compared with other controllers.
