Summary: This article presents a method for calculating all proportional-integral/proportional-derivative controllers with a given order low-pass filter that meet the requirements of gain-phase margins and sensitivity. The method is explicit and involves solving a set of polynomial and linear equations. The article also discusses extending the method to design proportional-integral-derivative or cascaded controllers with a low-pass filter when a minimum value of one of the controller components is given.

Summary: This paper proposes a joint methodology for performance assessment and retuning of PID controllers. The methods are based on data-driven approaches using set-point responses collected during operation or tests. Statistical tests are used to evaluate the performance and determine if retuning is needed. The proposed methodology can be applied to closed loops even with noisy signals and does not require prior assumptions about the controller design method.

Summary: This study compares a proportional-integral (PI) regulator with a parallel proportional-integral (PPI) regulator in a two-level pulse width modulation (PWM) inverter-fed Induction Motor (IM) drive. The IM drive is controlled by a modified field-oriented control (FOC) strategy using the PPI controller to improve performance. The FOC-PPI strategy is shown to be robust and efficient under parametric variations of the IM drive, as demonstrated through numerical simulations in Matlab/Simulink.

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 proposes a method for simultaneous tuning of cascade controllers to improve system performance under load disturbance. By formulating a cost function for a nonlinear optimization problem and defining robustness constraints, designers can explicitly and independently address the trade-off between performance and robustness.

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.
