On the Lyapunov Design of Systems with Zeros in the Right-Half Plane
The effect of a zero in the right-half plane on the controller derived through the stability theorem of Lyapunov is considered through a simple illustrative example. It is shown that the controller should have the form of a linear saturating function instead of the bang-bang form for the minimum-phase systems. Many industrial processes are known to exhibit a dead-time delay in their txansfer ch...
متن کاملInverted Decoupling Internal Model Control for Square Stable Multivariable Time Delay Systems
This paper presents a new tuning methodology of the main controller of an internal model control structure for n×n stable multivariable processes with multiple time delays based on the centralized inverted decoupling structure. Independently of the system size, very simple general expressions for the controller elements are obtained. The realizability conditions are provided and the specificati...
متن کاملA New Method for Time-Delay Compensation in Control Systems
In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
متن کاملAn Eigenvalue Characterization of Multivariable System Zeros
Since B (s) and d(s) are coprime, the proof is complete. From the lemma, the blocking zeros are seen to coincide with the roots, counting multiplicities, of q(s) = 0. For the sake of comparison, we remark that Rosenbrock [3] defines the zeros of G(s) to be the roots of cl(s)cz(s). . c,(s)=O. Desoer and Schulman [ I ] and Wolovich [2], without specifying multiplicities, identify the roots of c,...
متن کاملRobust Sliding Mode Control of Multivariable Time-Delay Systems
In this paper, the problem of sliding mode controller design for uncertain multi-input systems with several fixed state delays is addressed. A combined sliding mode controller is considered and it is designed for the stabilization of perturbed multi-input timedelay systems with matched parameter uncertainties and external disturbances. Delay-independent stability conditions are derived by using...
