In this paper, a new approach to the sliding-mode control of single-phase inverters under linear and non-linear loads is introduced. The main idea behind this approach is to utilize a nonlinear, flexible and multi-slope function in controller structure. This non-linear function makes the controller possible to control the inverter by a non-linear multi-slope sliding surface. In general, this sl...

This paper presents the position tracking performance of an electro-hydraulic hydraulic servo (EHS) system using sliding mode control (SMC) with proportional-integral-derivative (PID) sliding surface. In modelling process, a mathematical model of the EHS system is developed by considering its nonlinearities as represented by a Lu-Gre friction model. The control strategy is derived from the deve...

In this article, a novel systematic approach is proposed for partial sliding mode controller (SMC) design and tuning in non-minimum phase switch-mode power supplies (SMPS). To achieve more simplified comparison with the conventional SMCs, SMC (PSMC) introduced which just requires part of surface formulation. The accuracy developed PSMC proved mathematically within entire range operation. Since ...

In this paper, the problem of robust stabilization and chaos suppression of nonlinear chaotic brushless dc motors (BLDCMs) is investigated. We propose a PSO-based robust sliding mode controller for stabilization and chaos suppression of the BLDCM in the presence of both unknown model uncertainties and external disturbances. First, based on the Lyapunov stability theory, a robust SMC is designed...

Abstract Sliding Mode Control (SMC) is a powerful methodology in the field of nonlinear feedback control with feature of proven robustness, performance and stability in the face of system nonlinearity and modeling uncertainties. Unfortunately, pure SMC controller suffers from two important problems; chattering phenomenon and formulation of equivalent dynamics. The aim of this paper is to design...

in this paper, a new robust controller based on geometric homogeneity and adaptive integral sliding mode is proposed for a class of second order systems. the upper bound of the system disturbances is not required. fully unknown parameters have been considered in the described model and its finite–time convergence to zero equilibrium point is proved. moreover, the controller is developed in the ...

In this note, we propose two uniform sliding mode controllers (SMCs) for a second-order uncertain system. They provide convergence to an arbitrarily small vicinity centred at the origin in finite time, which can be bounded by some constant independent of the initial conditions and uncertainties. Towards this aim, a non-linear sliding surface is designed ensuring convergence, during the sliding ...

In this paper, sliding mode controllers (SMC) are designed for a steerable tractor-trailer system, which is operating in the presence of longitudinal and lateral slips at front and rear wheels. Such vehicles intended for autonomous operations usually traverse at low speeds along straight lines. As very low accelerations are involved kinematic models seem sufficiently accurate for developing con...

This work aims the precise control of the piezoelectric actuators that can theoretically provide unlimited motion resolution. For this purpose Sliding Mode Controller (SMC) is used. The proposed algorithm is known to have order of sampling time square and therefore faster application than DSP was required. The application of the algorithm via analog electronics is suggested.
