Summary: This paper presents an analytical study on first-order unstable plants under PID control, using a multiplicity-induced dominancy (MID) strategy to design and tune PID controller gains. The study shows desirable properties in terms of decay rate and stability robustness of the closed-loop system. Additionally, a tradeoff between delay robustness and tracking performance of PID controllers is investigated.

Summary: This article addresses the pole-placement issue for linear multi-input multi-output (MIMO) dynamic systems with uncertain parameters. By solving the optimization problem with constraints and using the Rayleigh quotient to solve the eigenvalue optimization problem, a feedback matrix design is achieved. The Monte Carlo simulations demonstrate lower covariance for closed-loop poles (CLPs) around the mean poles compared to a robust pole-placement method.

Summary: This paper proposes a new concept for designing PID controllers using dominant pole placement method and a derivative filter. By mapping the design onto the discrete time domain with a suitable sampling time, the continuous time delays can be converted into discrete time poles. The continuous-time plant and the filtered PID controller are discretized using the pole-zero matching method. Global optimization method is used to discover the stabilizable region and meet the pole placement conditions. Simulation results on test-bench plants demonstrate the validity and effectiveness of the proposed control design method.

Summary: This paper investigates the reduction of noise in a plate-cavity coupled system using active control based on the pole placement method. The effectiveness of the pole placement method in reducing noise in the coupled system is analyzed through theoretical derivation and solving a coupled matrix equation to calculate the sound field. The results show that the pole placement method is effective in controlling both the vibration and the vibro-acoustics in the plate-cavity coupled system.

Summary: This paper considers the problem of robust pole placement in active structural vibration control using the receptance method. Expressions for the eigenvalue sensitivities to parametric perturbations are derived and subsequently minimised to improve the performance robustness of the control system. The proposed algorithm includes curve fitting and polynomial fitting techniques to calculate the eigenvalue sensitivity from the structural frequency response functions, avoiding modelling uncertainty.

Summary: This work focuses on the design of state-feedback and static output-feedback controllers for uncertain discrete-time systems using reinforcement learning (RL) method. A State-Action-Reward-State-Action (SARSA) algorithm is developed to achieve this goal. The method utilizes gain matrices directly as design variables and employs a time-varying incremental step. It also uses a grid in the uncertain parameters to place the poles of the closed-loop system in a disk on the complex plane. The efficacy of the method is demonstrated through numerical experiments and stability testing based on Lyapunov theory.

Summary: This paper proposes new approaches for robust static output feedback (SOF) controller design for linear systems with polytopic uncertainty and linear parameter varying (LPV) systems. The methods utilize linear matrix inequality (LMI) techniques to ensure pole placement, H-2, and H(infinity) constraints, and can be applied to general linear systems without imposing constraints on system matrices. The effectiveness and performance of the proposed methods are demonstrated through two examples.
