In this paper, an innovative predefined‐time tracking control algorithm is proposed for high‐order nonlinear systems with control saturation and disturbance, which can directly calculate the upper bound of settling‐time by user‐defined parameters. First, a predefined‐time observer based on tracking differentiator is applied to handle the disturbance. Next, a new predefined‐time tracking control algorithm...
In this paper, high reliability radiation hardened On-Board Computer system using reconfigurable FPGA is investigated for space application. To avoid the influence of single event effects caused by an energetic particle in space, a new design scheme of high reliability OBC system is proposed using two FPGA chips and four DSP chips. The overall structure is based on redundant and reconfigurable technologies...
Super-resolution reconstruction for image sequences is a promising image processing technology that using complementary information among a set of images to reconstruct a high-resolution image. Several super-resolution reconstruction algorithms have been studied in the literature to reconstruct a high-resolution image. In this paper, first, after presenting a condensed introduction of image registration...
A maximum power point tracking (MPPT) controller for variable speed wind energy conversion system (WECS) is proposed. The proposed method, without requiring the knowledge of air density, wind speed and turbine parameters, generates at its output the optimum speed command for speed control loop of rotor flux oriented vector controlled grid side inverter control system using only the instantaneous active...
It is time consuming to design a complex system which has multi-function and mutual exclusion. In this paper, the design which flows of complex control system with Mutual Exclusion is divided into abstraction route and embodiment route. In the abstraction route, functions of the system are transferred to processes by using obtained or innovated algorithms and the processes are divided into modules...
