This paper proposes an automatic tuning algorithm for a sliding mode controller (SMC) based on the Ackermann's formula, that attenuates structural vibrations of seismically excited building equipped with Active Tuned Mass Damper (ATMD) mounted its top floor. The switching gain and surface SMC are designed through proposed to suppress by minimizing either floor displacement or control force appl...

This paper studies the trade-off between degree of decentralization and performance a distributed controller in linear-quadratic control setting. We study system interconnected agents over graph controller, called -distributed control, which lets make decisions based on state information within distance underlying graph. can tune its using parameter thus allows characterization relationship per...

The proposed controller constructively synergizes Proportional Integral Derivative (PID) Linear Quadratic Regulator (LQR) by taking their weighted sum. Particle Swarm Optimization (PSO) algorithm is op...

Area control error (ACE) is a critical factor in linked power systems. When disturbance occurs, ACE utilized to determine how much should be deployed. As result, it that the have as little inaccuracy feasible. This research provided strategy for improving dynamic response of system. A hybrid optimal controller name given this technology. Coordination between proportional-integral (PI) and state...

Present work aims at developing an active suspension for a passenger car by designing a controller using linear quadratic optimal control theory, based on two different control approaches [conventional method (CM), acceleration dependent method (ADM)]. Performance of the active suspension system of a quarter car model with 3 degrees-of-freedom with two control approaches has been compared with ...

In this work, the boundary control of a distributed parameter system (DPS) modeled by parabolic partial differential equations with spatially varying coefficients is studied. An infinite dimensional state space setting is formulated and an exact transformation of the boundary actuation is realized to obtain an evolutionary model. The evolutionary model is used for subsequent linear quadratic re...

ABSTRACT In this paper, a discrete sliding mode controller with multirate output feedback is designed to control the inverted pendulum system at the upright position. Most of the SMC control strategies are based on state feedback, however not all of the state feedbacks are available. The multirate output feedback (MROF) used output feedback, therefore the state are always available at any condi...
