This paper presents the optimization of a variable structure controller based on a decentralized fuzzy logic sliding mode (DFLSM) strategy for the control of the pitch and azimuth angles of a TRMS when coupling vertical and horizontal axes. Particle Swarm Optimization (PSO) algorithm is used to tune the DFLSMC parameters to ensure optimal performance in the closed loop, within a given cost function...
Massive Multiple-Input Multiple-Output (MIMO) is an emerging technology for the future 5G wireless communication systems and has been expected to dramatically improve the performance over the years. The main aim of this paper is to investigate the ergodic capacity of the downlink massive Multi-User (MU-MIMO) system under spatially correlated Rayleigh fading channels using two correlative models, namely...
This paper focuses on the synthesis of adaptive fuzzy fault tolerant controller which combines a sliding mode controller and a Proportional Integral controller (PI) for a class of MIMO underactuated nonlinear systems with external disturbances. The proposed control law treats the underactuated systems on their original non square form without squaring them by adding or eliminating variables. The uncertain...
In this paper, a discrete terminal sliding mode controller (DTSMC) is proposed based on a new nonlinear sliding function. This strategy of control is developed using only the input-output (I/O) model. To improve the effectiveness of DTSMC, we applied it to a DC-DC buck converter. The results obtained by simulations are given at the end to demonstrate the effectiveness of our proposed scheme in terms...
