The inverted pendulum system has been widely studied to test control techniques of nonlinear systems. We introduce a new alternative to control systems with complex dynamics, based on evolutionary game theory. Specifically, we use dynamics that are represented by the replicator equation, which has been successfully used in autonomous systems, control flight, and temperature control. Simulation results...
This paper presents an approach to design type- 2 fuzzy logic controllers (FLCs) for dynamic positioning (DP) systems, and the design process can be easily extended to other multi-input multi-output (MIMO) systems with coupling between loops. The combination of FLCs and nonlinear observers removes the need to linearize the kinematic equations of motion when designing control systems for the DP systems...
A method to design a high performance robust tracking controller to track step references for uncertain continuous MIMO plant is presented. A non-linear sliding surface is proposed by which the damping ratio of closed loop system is increased as output approaches setpoint. Stability with the proposed non-linear surface is proved. A new control law is designed to guarantee the existence of sliding...
This paper presents the controller synthesis for a fine actuation system of a 3-DOF micro parallel positioning platform. The platform is composed of a dual stage servo system for realizing both long stroke and high precision, simultaneously. Among the dual stage, the fine actuation system is more important as it guarantees high speed and accuracy. First, a physics-based model for the fine actuation...
This paper deals with the servo system design for hard disk drives using the approaching index switching algorithm introduced in [1]. The index represents a closed loop measure of the closeness of the system output to the reference set value. A switching algorithm is designed to switch between two different control sets according to the value of the index. The first control set is supposed to be suitable...
