This paper presents a design method for discrete-time parallel with continuous-time design for the two degree of freedom (2DOF) control system using PID (Proportional-Integral-Derivative)×(n-2) stage PD as a cascade controller for a class of nth order plant. Both, transient and steady state response specifications are suddenly met when the forward controller is employed. The root loci of this method...
This paper presents an application of the continuous-time deadbeat control, which is proposed recently based on the finite pole assignment for linear systems with time delay. The control object used here is a carriage, which is build with LEGO MINDSTORMS NXT as a model of crane for LCD manufacturing line. The implementation includes modeling, design, and implementation for a cheap microprocessor for...
Adaptive control systems are designed to achieve desired control performance when plant parameters gains are unknown, or possibly slowly changing. Highly calculation technology is developed, more important discrete-time adaptive control structure is. Because the relative degree condition for strict positive realness (SPR) of the discrete-time error transfer function is different from the condition...
In this paper, a novel design approach based on time-response resemblance of the closed-loop system via particle swarm optimization is proposed to improve performance of the redesigned digital system for continuous-time uncertain interval systems. The design rationale of the proposed approach is to derive a digital controller for the redesigned digital system so that step response sequences corresponding...
