In this paper, we propose an adaptive control scheme for a class of nonlinear time-delay systems. To alleviate the requirement for accurate modeling of the plant, a two-level robust control scheme was proposed. The inner-level adaptive neural controller is responsible for accurate servo control, while the outer-level supervising controller compensates for un-modeled system dynamics and bounded disturbances. Besides, each part of the proposed control law can be independently designed satisfying its own specifications. The number of unknown parameters is significantly reduced by using the neuron-like models. Moreover, the supervising control law and adaptation gains are designed based on stability conditions in the sense of Lyapunov. The scheme is readily applicable to temperature control systems where heat transfer and mass transportation cause significant delay effects. Experimental results collected from a prototype temperature regulation system verify effectiveness of the proposed scheme. Performance improvement of feed-forward control term is also clearly demonstrated.

This research article exhibits a utility grid-interfaced solar photovoltaic (SPV) system for power quality enhancement. An adaptive proportional integral derivate (APID) controller with a unit vector template (UVT) is employed to generate a reference current signal of a shunt active power filter (APF). The UVT-based control scheme is used to separate the fundamental components from the load currents and to estimate the reference phase currents. These currents are used to generate pulse width modulation signal for the shunt APF. To maintain a constant dc link voltage of shunt APF, an APID controller is employed in the dc link voltage regulator. This extended reference signal generation scheme of shunt APF remarkably enhances the system performance and also diminishes the current and voltage harmonics in the power distribution system. The presented reference current generation scheme has been mathematically examined, and digital simulation results under different steady and dynamic states are presented. The SPV system is accomplished by utilizing the incremental conductance maximum power point technique and is interconnected with the utility grid. Finally, the entire system is validated through the real-time hardware prototype developed by using dsPIC30F4011.
