A new technique of designing a robust PID and Polynomial controller for DC motor speed control is proposed. The proposed approach poses the design problem as fixed structure robust controller and mixed sensitivity H ∞ method. Performance weights are designed based on the closed-loop objective and performance requirements which are normally applied in H ∞(More)
The objective of the paper is to design the robust discrete H ∞ controller for dc motor position control using Frequency-Domain Robust Controller Design Toolbox. In this paper, the time performance characteristics of 2 nd and 3 rd order controller has been compared by taking dc motor as a design example. The paper aims at demonstrating and simple modelling(More)
This paper presents a design methodology for two degrees of freedom (2-DOF) observer based controller for the integral processes with dead time. The 2-DOF controller structure facilitates independent design for feedback properties and set point tracking. The feedback controller aims to achieve stability, robustness and disturbance attenuation whereas(More)
In this paper particle swarm optimization(PSO)has been applied for the design of the optimal robust controllers for third order systems. The controller design problem is posed as constrained nonlinear optimization problem. The parameters of the chosen controller are obtained solving the nonlinear constrained optimization problem.The performance index which(More)
