“…Because the LMPC method uses a simpler design, the computational load is reduced. The performance improvements of a PMSM designed using the LMPC are compared with those designed using the algorithm presented in a different studies [20,21]. (3) To achieve a lower computational load and minimize the numerical problem, this paper proposes an exponentially decreasing objective function for the LMPC, specifically for a large prediction horizon to control the speed of the PMSM.…”

This paper proposes a model predictive speed control strategy for a surface-mounted permanent magnet synchronous motor by applying Laguerre functions. The model predictive controller (MPC) incorporates an integrator. A quadratic programming procedure is applied to solve the constrained optimization problem online. The paper also provides a solution for stability. The performance efficiency of the proposed scheme is validated by comparing the results with the performance of an optimal linear quadratic regulator, conventional state-space model predictive control, and a simple MPC algorithm with integral action. Extensive simulation results confirm the efficacy of the proposed scheme, showing that it achieves good steady-state performance while maintaining a fast dynamic response.

“…In (Cheng et al, 2016), the output voltage of the DC-DC converter was regulated to the desired voltage through the fast and finite-time adaptive method. In (Abdissa & Chong, 2017), the model predictive control method is proposed to control the output voltage of the DC-DC converter. In (Bhattacharyya, Padhee, & Pati, 2019), the authors utilized the feedback linearization method to control the output voltage of the step-down converter.…”

The buck converter is widely utilized in various applications such as solar chargers, electrical vehicles and space exploration. The use of an efficient controller in buck converters reduces the heat and losses, extends the useful life, and allows for smaller gadgets to be built. In this research, a novel technique is proposed to regulate the output voltage of the buck converter. For this purpose, the mathematical model of the converter is introduced. Next, the adaptive sliding mode is suggested to regulate the output voltage. In order to ensure the faster transient response and finite-time convergence, the terminal sliding mode control is suggested. The singularity problem is solved by using nonsingular terminal sliding mode control. The switching gain is adaptively scheduled according to the fuzzy logic system. Finally, some simulation results including the parametric uncertainties, measurement noise, and steady-state error analysis are illustrated to demonstrate the efficiency of the proposed controller.

The three-phase voltage source inverter has been widely used in a number of industries in the recent years. Although the control technique of the three-phase voltage source inverter has been growing toward maturity, research into obtaining a better steady-state performance is still a hotspot. In this paper, a modified controller is proposed to control the three-level, three-phase voltage source inverter with a resistive-inductive load. The controller uses Laguerre functions to modify the model predictive control in order to reduce the computation burden and obtain more precise results. Then the required reference voltage can be calculated by the modified model predictive control with the voltage detection of the load and the current compensation. The required reference voltage will be used to determine the switching sequences by space vector pulse width modulation. Extensive experiments demonstrate that the modified controller can help a three-level, three-phase voltage source inverter with resistive-inductive load to achieve low total harmonic and better steady-state performance.
