Summary: This study presents an adaptive PI and RBFNN-PID current control solution for PMSM drives. The proposed controller includes four controls: a decoupling term, a PI term, a supervision term, and a RBFNN-PID term. It can handle nonlinear factors, automatically adjust control gains, guarantee system stability, and optimize PID parameters. The experiment confirms the good robustness and excellent control stability of the proposed design.

Summary: In the teaching process, it is important for students to conduct real-time research rather than rely solely on computer simulations. However, during distance learning in the COVID-19 pandemic, finding a solution for students to individually perform such exercises at home becomes necessary. This paper presents a low-cost proportional-integral-derivative (PID) controller based on Arduino or STM32 microcontroller modules, which allows students to learn control techniques and analog control objects in real time. The digital PID controller algorithm is calculated at regular intervals, making it an effective solution for remote learning during the pandemic.

Summary: This paper proposes a stochastic discrete-time multivariable proportional-derivative-double derivative (PDD) controller to improve system robustness and relative stability. The study shows that the mean-square velocity error is inversely proportional to the square of the sample rate. Experimental results demonstrate the tracking superiority of the proposed control.

Summary: The proposed PID-incorporated SGD-based LFA (PSL) model accelerates model convergence by rebuilding instant errors based on the PID principle. Empirical studies show that the PSL model achieves significantly higher computational efficiency and competitive prediction accuracy for missing data in high-dimensional and sparse matrices compared to state-of-the-art LFA models.

Summary: This article presents a robust hybrid linear quadratic regulator (HLQR) controller for unmanned free-swimming submersibles (UFSS) to overcome environmental disturbances and sensor noise, targeting the desired state of the UFSS. The controller employs two linear quadratic regulators and a mathematical structure of the Riccati equation for a hybrid approach, outperforming existing controllers in terms of settling time, rise time, overshoot, and steady-state error. The robustness of the HLQR is validated through feedback to step response and hydrodynamic disturbances.

Summary: This paper presents an analysis of a quadcopter's stability and its sensors' data reading using an IMU (inertial measurement unit). The quadcopter's control was achieved by connecting a brushless DC motor to an Stm(& REG;) development board. A combination of barometric pressure and temperature sensors determined the altitude of the quadcopter. The PID (proportional-integral-derivative) controller and Simulink software were utilized for parameter adjustment and simulation, respectively, to ensure flight stability and improve remote machine module efficacy.

Summary: This paper presents a design framework for obtaining a robust multivariable PID controller for second-order linear vibrating systems. It also proposes a PIDA controller to address the regularization problem. Control challenges such as modeling error, regulatory performance optimization, regional pole placement, saturation avoidance, and constant reference tracking are handled using a Linear Matrix Inequality design approach. The design strategy involves a linear transformation for achieving constant reference tracking in an actuated subspace. The integral action has additional objectives of improving regulatory performance in the presence of constant disturbance and increasing design degree of freedom.

Summary: This paper investigates the internal resonance of a circular dielectric elastomer membrane under mechanical and electrical excitations to improve its performance for future applications. A time-delayed proportional-derivative (TDPD) controller is proposed to reduce the oscillations of the DE system and improve stability and transient response. The first-order approximation solutions of the DE system are calculated and the dynamic solution with TDPD controllers is obtained using analytical and numerical approaches.
