To improve the overall dynamic performance of induction motor in direct torque control (DTC), a novel method of stator resistance estimation based on multi-resolution analysis wavelet PI controller is presented. This estimation method is anchored in an on-line stator resistance correction regarding the variation of the stator current estimation error. The main purpose is to adjust precisely the...

In this paper, a novel method is developed for designing the output feedback controller for Static Synchronous Series Compensator (SSSC). In the proposed method, the problem of selecting the output feedback gains for the SSSC controllers is changed into an optimization problem with a time domain-based objective function.Then, it is solved by using the particle swarm optimization (PSO) algorithm...

Robust control design of vehicles addresses the effect of uncertainties on the vehicle’s performance. In present study, the robust optimal multi-objective controller design on a non-linear full vehicle dynamic model with 8-degrees of freedom having parameter with probabilistic uncertainty considering two simultaneous conflicting objective functions has been made to prevent the rollover. The obj...

This paper proposes a predictor-based state feedback controller for multi-input linear time-invariant (LTI) systems with different time delays in each individual input channel. The controller is derived based on the backsteppingmethod. Since the conventional backstepping transformation is not applicable to the systems due to the differences among delays, a modified transformation is introduced....

This paper presents an integral high order sliding mode controller for a class of multi-input, multi-output nonlinear uncertain system. After transforming the system into high order input-output dynamic system, the idea is to define an integral sliding surface based on a nominal control law designed to stabilize in finite time the unperturbed system. By imposing some conditions on the controlle...

This paper proposes a necessary and sufficient condition of convergence in the 2 L norm sense for a feedback-based iterative learning control (ILC) system including a multi-input multi-output (MIMO) linear time-invariant (LTI) plant. It is shown that the convergence conditions for a nominal plant and an uncertain plant are equal to the nominal performance condition and the robust performance co...

This article introduces a novel distributed controller approach for networked control systems (NCS) to achieve finite gain L2 stability independent of constant time delay. The distributed controller is alternatively interpreted as a linear transformation of the inputoutput space of the controller and the plant, and in fact represents a generalization of the well-known scattering transformation....
