  • This paper proposes an adaptive robust Fuzzy controller based on Backstepping scheme to solve with the model unknown and parameter disturbances for robot manipulator. In this research, the robust adaptive fuzzy system is combined with Backstepping design method to remove the matching condition requirement and to provide boundedness of tracking errors, even under dominant model uncertainties.

  • The efficient and effective speed controllers can be designed by using adaptive control techniques. In which the conventional PI controller is replaced by structures based on Sliding Mode Control (SMC) strategy. SMC is known for its capability to cope with bounded disturbance as well as model imprecision which makes it ideal for the robust nonlinear control of IM drives.

  • This article highlights a robust adaptive tracking control approach for a nonholonomic wheeled mobile robot by which the bad problems of both unknown slippage and uncertainties are dealt with. The radial basis function neural network in this proposed controller assists unknown smooth nonlinear dynamic functions to be approximated. Furthermore, a technical solution is also carried out to avoid actuator saturation. The validity and efficiency of this novel controller, finally, are illustrated via comparative simulation results.

  • Direct MRAS offers a potential solution to reduce the tracking errors in the presence of uncertainties and variation in plant behavior. However, this control algorithm may fail to be robust to measurement noise. In order to solve this trouble, the indirect MRAS is introduced that permanently adjust the parameters of observers. The adaptive adjusting law is derived by applying Lyapunov theory. The adaptive algorithm that is shown in this paper is quite simple, robust and converges quickly. Performances of the controlled systems are studied through simulation in Matlab/Simulink environment.

  • The ANFIS is thus employed to eliminate the chattering and simultaneously the HTSS provides finite system-state convergence time. By combining HTSS with ANFIS, the DC-AC power converter of AMM will achieve robust performance. Experimental results are given to conform that the proposed technique can obtain low total harmonic distortion (THD) and fast transience even under phase-controlled loads.

  • The theory of switched systems concerns hybrid dynamical systems composed of a family of continuous–time subsystems and a switching law, orchestrating switching between these subsystems. Systems of this class have been identified in many natural and man– made systems, and are recently widely studied by control theorists, computer scientists, practicing engineers and others.

  • In this paper, the authors propose a novel adaptive multilayer T-S fuzzy controller (AMTFC) with a optimize soft computing algorithm for a class of robust control uncertain nonlinear SISO systems. First, a new multilayer T-S fuzzy was created by combined multiple simple T-S fuzzy model with a sum function in the output. The multi-layer fuzzy model used in nonlinear identification has many advantages over conventional fuzzy models, but it cannot be created by the writer's experience or the trial and error method. It can only be created using an optimization algorithm.

  • This work deals with the control design and development of an automated car-following strategy that further increases robustness to vehicle dynamics uncertainties. The control algorithm is applied on a hierarchical architecture where high and low level control layers are designed for gap-control and desired acceleration tracking, respectively. A fractional-order controller is proposed due to its flexible frequency shape, fulfilling more demanding design requirements.
