Abstract Control system design for inverter fed drives previously used the classical transfer function approach for single-input singleoutput (SISO) systems. Proportional plus Integral (PI) controllers were designed for individual control loops. It is found that the transient response of a PI controller is slow and is improved by pole placement through state feedback. However, the effective gai...
natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...
Proportional-integral-derivative (PID) controller is the most widely used in industry due to its simplicity and performance characteristics. However, a number of processes with time-variant or nonlinear characteristics are difficult to be handled with a conventional PID controller. To address this problem, an enhanced PID controller exhibiting improved performance than the conventional linear f...
The problem of stabilization for uncertain systems has been widely investigated for many years [1–11]. In these studies, the origin was not supposed to be an equilibrium point of the uncertain system. So we can no longer expect to design a controller that guarantee the stability of the origin as an equilibrium point. In [1], a class of state feedback controls is proposed in order to guarantee u...
In this paper a methodology to develop a fuzzy rule-based controller is described. The rulebase is obtained by learning from a virtual feedback (PID) controller. The designed controller is supposed to support typical control requirements (i.e. fast-following, zero steady state error, overshoot suppression, etc.) using only a small number of rules. The virtual controller is designed by manual ad...
In this paper we develop an intelligent controller on the basis of Genetic Algorithms for the stabilization of a class of Underactuated Mechanical Systems. First we develop a static State Feedback Controller with inner noncollocated partial feedback linearization loop to stabilize the nominal system. Second, we develop a Genetic algorithm controller to maintain system stabilization and to adapt...
In this paper new necessary and sufficient conditions for static output feedback stabilizability for continuous and discrete time linear time invariant systems have been proposed. These conditions are the basis for the procedure of static output feedback controller design proposed in this paper. The proposed LMI based algorithms are computationally simple and tightly connected with Lyapunov sta...
A controller is presented for point stabilization of the extended chained form system. The extended chained form system can not be stabilized by means of continuous pure-state feedback. Moreover, it can not be exponentially stabilized by smooth feedback, since the linearization around equilibrium points is uncontrollable. In this paper, a controller is given that ρ-exponentially stabilizes the ...
The objective of the paper is to propose an approach to decentralized networked quantized state feedback H∞ controller design for a class of complex symmetric composite continuous-time systems. The effect of data-packet dropouts and communication delays between the plant and the local controller as well as quantizers design are included in the design of asymptotically stabilizing controller and...
This paper is concerned with the H∞ state feedback control problem for a class of nonlinear stochastic systems with time-varying state delays. Firstly, the stochastic dissipativity of the time-delay nonlinear system is established, based on which the H∞ state feedback controller is synthesized. We show that the closed-loop system rendered by the designed controller can achieve the L2-gain perfo...
