“…Figure 4 shows the root locus plot for the outer position loop as a function of the gain K p for K v = 10, α = 100, and f 0 = 10Hz. Figure 5 shows the upper boundary curves obtained from the conditions in (39). It can be observed that boundary condition E p > 0 is the dominant curve to limit the value of K p .…”

“…Model reference adaptive control (MRAC) has also been used in the literature to control servo-drive systems without prior knowledge about the system parameters [37][38][39]. MRAC is a control method that uses a reference model to generate a desired response, and the control action is adjusted in real time based on the difference between the actual response and the desired response.…”

This paper presents a new sinusoidal position-tracking control scheme with a resonant controller for linear motor drive systems. The sinusoidal tracking controller is designed without any added algorithm for system identification and requires only approximate values of the mechanical parameters. Therefore, the controller is simple and robust to parameter variations. The proposed sinusoidal tracking resonant-based controller (STRC) is designed to track reference positions using a cascade control structure with an inner current/force control with hysteresis current control followed by a speed control loop with a resonant controller, and an outer position loop with a proportional and velocity-feedforward controller. The stability of the cascade feedback scheme and its parameter tuning are analyzed using the Routh–Hurwitz criterion. The performance of the proposed control scheme is validated using simulations and experiments on a voice-coil linear stage. The proposed STRC strategy is characterized by ease of implementation and shows excellent performance with fast response and high accuracy at different frequencies with a maximum error of 0.58% at 0.25 Hz.

“…In order to cope with the increasingly challenging voltage regulation problem, experts and scholars at home and abroad are actively looking for different voltage regulation measures and methods. In the reference [2], the adaptive control of microgrid voltage is achieved by using a direct model of boost converter. The reference [3] uses distributed energy storage system to regulate the bus voltage and control the bus voltage fluctuation of DC microgrid.…”

Although the current regulation of user-side voltage takes into account the needs of users, it mostly adopts rigid regulation, which leads to the increase of carbon emissions in energy consumption of the power grid. In order to improve the above defects and maximize the energy saving of the power grid, a flexible adjustment method for the voltage on the large power user side under the constraint of carbon emission is studied. Through the establishment of user side zip model, the user side voltage flexible control load is analyzed. Taking energy consumption, power factor, three-phase imbalance and time sharing as indicators, the carbon emission constraints of power supply are calculated. Based on the actual demand response of the user side, the hierarchical coordinated control of voltage is realized. In the power grid experiment, the regulation method under the constraint of carbon emission can reduce the carbon emission, and the power energy loss during regulation is reduced by about 3/8 on average, and the practical application effect is better.

“…In [4], a centralized model predictive control has been developed to stabilize the DC microgrid with versatile buck-boost converters. A direct model reference adaptive control [5] and an optimal adaptive control [6] have also been presented for boost and voltage source converters, respectively. A nonlinear control based on the Lyapunov function has been developed in [7] for power management systems, whereas an inverse-system decoupling control method has been presented in [8] for a dc-dc buck-boost converter.…”

The pulse-with modulated (PWM) dc-dc buck-boost converter is a non-minimum phase system, which requires a proper control scheme to improve the transient response and provide constant output voltage during line and load variations. The pole placement technique has been proposed in the literature to control this type of power converter and achieve the desired response. However, the systematic design procedure of such control law using a low-cost electronic circuit has not been discussed. In this paper, the pole placement via state-feedback with an integral control scheme of inverting the PWM dc-dc buck-boost converter is introduced. The control law is developed based on the linearized power converter model in continuous conduction mode. A detailed design procedure is given to represent the control equation using a simple electronic circuit that is suitable for low-cost commercial applications. The mathematical model of the closed-loop power converter circuit is built and simulated using SIMULINK and Simscape Electrical in MATLAB. The closed-loop dc-dc buck-boost converter is tested under various operating conditions. It is confirmed that the proposed control scheme improves the power converter dynamics, tracks the reference signal, and maintains regulated output voltage during abrupt changes in input voltage and load current. The simulation results show that the line variation of 5 V and load variation of 2 A around the nominal operating point are rejected with a maximum percentage overshoot of 3.5% and a settling time of 5.5 ms.
