This paper proposes a new adaptive controller for the robust control of a grid-connected multi-DG microgrid (MG) with the main aim of output active power and reactive power regulation as well as busbar voltage regulation of DGs. In addition, this paper proposes a simple systematic method for the dynamic analysis including the shunt and series faults that are assumed to occur in the MG. The pres...

The paper deals with the synthesis of a non-fragile state controller with reduced design complexity for a class of continuous-time nonlinear delayed symmetric composite systems. Additive controller gain perturbations are considered. Both subsystems and interconnections include time-delays. A low-order control design system is first constructed. Then, stabilizing controllers with norm bounded ga...

This paper presents a real time implementation of a sliding mode controller (SMC) for the underactuated BERUL fingers. The use of SMC is to deal with the inaccuracies and unmodelled nonlinearities in the dynamic model of the robotic fingers, in particular, to overcome significant friction and stiction. This paper in particular shows a practical implementation of Cartesian space control for the ...

The development of a fuzzy-logic controller for a class of industrial hydraulic manipulator is described. The main element of the controller is a PI-type fuzzy control technique which utilizes a simple set of membership functions and rules to meet the basic control requirements of such robots. Using the triangle shaped membership function, the position of the servocylinder was successfully cont...

A new iterative method using closed-loop data for controller tuning based on the correlation approach is proposed. The main idea is to make the output error between the closed-loop system and a reference model uncorrelated with the reference signal. The controller parameters are calculated as the solution to a correlation equation involving instrumental variables. Convergence and consistency of...
