An adaptive and sliding-mode observer (SMO) is designed for the incipient fault of guided missiles with unknown disturbance, which can not only estimate the incipient fault, but also have strong robustness against unknown disturbance. At first, the actuator fault and unknown disturbance are transformed into two subsystems by coordinate transformation; and then, an adaptive observer is designed to...
Nonlinear model predictive control algorithm based on hierarchical optimization is used in this paper to solve the thorny problems of controlling the pH, such as highly nonlinear and large time-delay which have been hard to be settled by the conventional PID controller, in the neutralization process of rolling mills wastewater treatment. Furthermore, the hardware parameters and configurations are...
To overcome the common defects of early convergence in the existing genetic algorithm, an improved genetic algorithm with new crossover operator and new crossover strategy was presented for the solution to the vehicle routing problem with soft time window (VRPTW). Experiments show that the improved genetic algorithm can dramatically reduce the number of same or similar chromosomes, and increase the...
