Article Citation - WoS: 19Citation - Scopus: 28Obtaining Routh-Pade Approximants Using the Luus-Jaakola Algorithm(inst Engineering Technology-iet, 2005) Singh, VThe Routh-Pade approximation problem relating to the construction of a stable reduced-order (rth-order) approximant G(r)(s) for a given stable high-order (nth-order) transfer function G(s), so as to fully retain the first r time moments/Markov parameters of G(s) as well as to minimise the errors between a few subsequent time moments/Markov parameters of G(s) and those of G(r)(s), is revisited. For the solution of this problem, a novel computer-aided method based on the well known Luus-Jaakola algorithm is proposed.Article Citation - WoS: 22Citation - Scopus: 32Stability Analysis of Discrete-Time Systems in a State-Space Realisation With State Saturation Nonlinearities: Linear Matrix Inequality Approach(Iee-inst Elec Eng, 2005) Singh, VA computationally efficient linear matrix inequality (LMI)-based criterion for the global asymptotic stability of discrete-time systems in a state-space realisation with state saturation nonlinearities is presented. The criterion turns out to be an improved generalised version of a previously reported LMI-based criterion. The extension of the approach to a situation involving partial state saturation nonlinearities is performed.Article Citation - WoS: 5Citation - Scopus: 5Floating Operational Transconductance Amplifier Based Grounded Impedance(Iee-inst Elec Eng, 2003) Singh, VA technique to reproduce, in floating form, a given operational transconductance amplifier (OTA) based grounded impedance (GI) is presented. Unlike the back-to-back technique, the technique presented has the feature that the required additional matching constraints (i.e. in addition to those, if any, in the given GI) are independent of the original components, implying that the canonicity with regard to the number of capacitors and the single-element tunability, if any, in the given GI are fully retained in the resulting floating impedance.Article Citation - WoS: 14Citation - Scopus: 18Optimal Routh Approximants Through Integral Squared Error Minimisation: Computer-Aided Approach(inst Engineering Technology-iet, 2004) Singh, V; Chandra, D; Kar, HA computer-aided method for obtaining a reduced-order approximant of a given (stable) single-input single-output system based on the minimisation of integral squared error (ISE) pertaining to a unit-step input is presented. Both the numerator and denominator coefficients of the model are treated as free parameters in the process of optimisation. The method has a built-in stability-preserving feature. The problem of formulating the ISE is circumvented by introducing a set of equality constraints.Article Citation - WoS: 34Citation - Scopus: 42Stability Analysis of Discrete-Time Systems in a State-Space Realisation With Partial State Saturation Nonlinearities(Iee-inst Elec Eng, 2003) Kar, H; Singh, VA criterion for the global asymptotic stability of discrete-time systems in a state-space realisation with partial state saturation nonlinearities is presented. The criterion is compared with a previously reported criterion.Article Citation - WoS: 24Citation - Scopus: 27Global Asymptotic Stability of Cellular Neural Networks With Unequal Delays Lmi Approach(Iee-inst Elec Eng, 2004) Singh, VA criterion for the global asymptotic stability and uniqueness of the equilibrium point of cellular neural networks with unequal delays is presented. The criterion is computationally efficient, since it is in the form of linear matrix inequality (LMI).Article Citation - WoS: 50Citation - Scopus: 53Simplified Lmi Condition for Global Asymptotic Stability of Delayed Neural Networks(Pergamon-elsevier Science Ltd, 2006) Singh, VA linear matrix inequality (LMI) based criterion for the global asymptotic stability of a class of delayed neural networks is presented. The present criterion is a simplified version of the respective LMI based criterion recently given by Cao and Ho. (c) 2005 Elsevier Ltd.

The uncertainties are assumed to be norm-bounded. The criterion is computationally efficient, since it is in the form of a linear matrix inequality.Article Citation - WoS: 13Citation - Scopus: 16Equivalent Forms of Dual-Ota Rc Oscillators With Application To Grounded-Capacitor Oscillators(institution Engineering Technology-iet, 2006) Singh, VThe equivalent forms (i.e. possessing a common characteristic equation) of some classes of dual-operational transconductance amplifier (OTA) sinusoidal oscillators are brought out. The present results turn out to be an aid to a synthesis procedure previously given by Tao and Fidler for the generation of dual-OTA oscillators.
