  • Parameterised Wirtinger-based integral inequalities for the stability analysis of systems with time-varying delays
    Sharat Chandra Mahto
    Journal of Control and Decision, 2025
    This note presents two parameterised integral inequalities for the delay-dependent stability analysis of systems with time-varying delays. The Wirtinger-based integral inequality is parameterised using scalar parameters to introduce additional quadratic terms. These quadratic terms are utilised to exploit the interaction among constituent variables for the improved delay-dependent stability criterion. Some classical examples are considered to show the flexibility introduced by the parameterised inequalities.

  • Parametrised auxiliary function-based integral inequality for time delay system
    Sharat Chandra Mahto
    International Journal of Systems Science, 2024
    This paper employs two scalar parameters to extend auxiliary function-based integral inequality into a new formulations, say a parametrised auxiliary function-based integral inequality. Using these formulations, the constituent signals are utilised more efficiently by exploiting the interaction between them to reduce conservatism. Numerical example for stability analysis of linear systems with time-varying delay shows the improved performance of the proposed new formulations in terms of maximum delay bounds and decision variables.

  • Artificial Delayed Output Twisting Algorithm
    Shyam Kamal, Aishwarya Bharti, Xinghuo Yu, Durgesh Kumar, Sharat Chandra Mahto, Sandip Ghosh, X. Xiong
    IEEE Transactions on Circuits and Systems II Express Briefs, 2022
    For uncertain systems with relative degree two, an output feedback based twisting algorithm is proposed. This algorithm ensures practical asymptotic convergence to the origin based on the information of output and its artificially delayed version. We prove the convergence of the proposed algorithm by a continuous, weighted homogeneous and strict Lyapunov function.

  • Improved Stability Criteria for Time-Varying Delay System Using Second and First Order Polynomials
    Sharat Chandra Mahto, Rajvikram Madurai Elavarasan, Sandip Ghosh, R. K. Saket, Eklas Hossain, Shyam Krishna Nagar
    IEEE Access, 2020
    This paper concerns the problem of stability analysis of systems with time-varying delay. Recent developments in this direction involves approximation of a second order polynomial function of time-delay. This paper proposes a new Lyapunov-Krasovskii Functional that does not introduce the secondorder polynomial and thereby avoid the approximation involved in obtaining the stability criterion. Two stability criterion are presented, one introduces the second-order polynomial and the other one does not. A comparison using numerical examples shows that the avoidance of second-order polynomial formulation leads to improved results.
  • Nonsmooth PI Controller for Uncertain Systems
    Sharat Chandra Mahto, Durgesh Kumar, Shyam Kamal, Asif Chalanga, Xiaogang Xiong, Shanhai Jin, Shyam Krishna Nagar
    IEEE Access, 2020
    This paper investigates the problem of nonsmooth feedback stabilization for the higher order uncertain chain of integrators. For achieving the specified goal, the integral term of classical Proportional-Integral (PI) controller is replaced by an integral of the discontinuous function. Replacing this integrator, the overall control becomes absolutely continuous rather than discontinuous as in the first order sliding mode control. With this proposed scheme, the property of invariance concerning the matched Lipschitz uncertainty is still preserved. The main technical contribution of the paper is a sound and non-trivial Lyapunov analysis of the closed loop system controlled by nonsmooth PI controller. The effectiveness of the proposed controller is illustrated with the help of numerical simulation on the magnetic suspension system.
