“…Compared to other control methods, SMC has attracted significant interest due to its simplicity, low sensitivity to system parameter variations and high robustness to external disturbances [2]. Therefore, SMC has been developed and applied widely in many applications, including robot manipulators [3], cable-driven manipulators [4], [5], power systems [6], multiagent systems [7] and guidance law design [8].…”

This paper proposes a nonsingular terminal sliding mode control scheme with fast fixed-time convergence for a class of second-order nonlinear systems in the presence of matched uncertainties and perturbations. First, based on fixed-time stability theory, a novel stable system is proposed. Then, using the fixed-time stable system, a fast fixed-time nonsingular terminal sliding surface is derived. The settling time is independent of the initial system state and can be set in advance with the design parameters; the upper-bound of convergence time is derived from the Lyapunov theory. Moreover, the proposed control scheme has an advantage in convergence rate over existing results and achieves better control performance with low control energy cost. The simulation results for a tracking system with a single inverted pendulum are presented to validate the effectiveness and superiority of the proposed control method.

“…The tuning guidelines and applications of PSS with various signals are thoroughly discussed in Larsen and Swann . The design and practical application of PSS on the Ontario Hydro station are given in Kundur et al Useful PSS design methods on the multi‐machine environment are presented in Huwer et al, Gupta et al, and Gomes et al A number of PSS design techniques like robust control techniques, sliding mode control techniques, fuzzy sliding mode control techniques, optimization methods using LQR, H ∞ techniques artificial intelligence techniques such as fuzzy logic and neuro‐fuzzy techniques, linear control techniques such as pole placement techniques, nonlinear control techniques such as feedback linearization and adaptive control techniques had been developed by various researchers from the last two decades. Though they performed well in stabilizing the system, design of PSS for the multi‐machine power system using conventional techniques under variable operating conditions is a complex process and hence consume much computational time.…”

Summary An improved whale optimization algorithm (IWOA) for the design of a robust power system stabilizer (PSS) for the multi‐machine power system is developed in this paper. Tuning of PSS parameters using the proposed IWOA is carried out by minimizing a multi‐objective function comprising the damping ratio and damping factor of lightly damped oscillating modes of all the generators. The advantage of considering the objective function is that the lightly damped and undamped oscillating modes of all the generators can shift to a prespecified zone of the s‐plane. The performance of the proposed IWOA is tested on standard benchmark test functions and compared with familiar optimization algorithms. The efficacy of the proposed design technique is tested on three benchmark test systems: three‐generator nine‐bus system, two‐area four‐machine interconnected system, and the New England 10‐generator 39‐bus system working on various operating conditions under several typical disturbances. The potential of the proposed method is demonstrated through eigenvalue analysis. The proposed IWOA‐based PSS is compared with the other stabilizers to show its efficacy.

“…The robust switching techniques such as SMC demonstrate good performance in the presence of interactions and matched uncertainties (Shoja-Majidabad et al 2014;Ray et al 2018;Azizi et al 2019). Nevertheless, SMC illustrates chattering and poor performance versus the unmatched uncertainties.…”

In this paper, decentralized adaptive backstepping control of cascaded DC-DC boost converters is studied in the presence of load and voltage uncertainties and interactions between the converters. First, a cascaded boost converter average model that covers both continuous and discontinuous conduction modes is extracted. Afterward, flatness property is applied to transfer the cascaded system states into a semi-canonical form. Further, a novel decentralized backstepping controller is proposed to track the reference voltages. In this control strategy, Legendre polynomials are utilized to estimate the uncertainties and interactions adaptively. The control method is simple and robust with less computational burden due to the polynomial estimator's application. Various simulations are performed for the cascaded DC-DC boost converters to indicate the effectiveness and performance of the proposed controller under the load and supply voltage changes.
