Current real-time applications should timely deliver synchronized data-sets, minimize latency in their response and meet their performance specifications in the presence of disturbances and faults. The adaptive features of the designed controller are present at the lower control level using specific artificial intelligence techniques. Fuzzy inference system design is the fundamental element to generate...
This paper deals with the discrete-time adaptive output trajectory tracking for induction motors in presence of bounded disturbances. A recurrent high order neural network structure is used to design a nonlinear observer and based on this model, a discrete-time control law is derived, which combines discrete-time block control and sliding modes techniques. The paper also includes the respective stability...
This paper proposes a method to suboptimally tune the control parameters in a conventional Lyapunov-based method which shares the same concept of control design with sliding mode approach as applied to the robot manipulators. Optimal tuning of such parameters involves handling of nonlinearities in system dynamics and cost functions, which makes the problem challenging. We propose a step-by-step numerical...
In this paper, two nonlinear controllers for a single flexible link manipulator are presented. These controllers are derived using sliding mode technique. The first controller presented in this paper is a generalization of the computed torque which is used in conventional rigid robot control. In this method, we have assumed that the model parameters of the planar single flexible manipulator are perfectly...
Various robust control techniques, such as integral-block, sliding-mode, and H-infinity controls, are combined to design a controller, forcing an electrohydraulic actuator which is driven by a servovalve to track a chaotic reference trajectory. This approach enables one to compensate the inherent nonlinearities of the actuator and reject matched external disturbances and attenuate mismatched external...
