In order to solve the uncertainty problem of parameter variations and load disturbance which effect on the system performance, a nonlinear adaptive inverse decoupling control based on disturbance suppression is presented for the PMSM drive system. The method combine adaptive control with nonlinear decoupling control, and the parameter variations and load disturbance are disturbance input. The state...
A novel hybrid learning algorithm based on a genetic algorithm, named simulated annealing genetic algorithm, is put forward in this paper to solve the optimization model of (N+M) fault-tolerant systems. A new adding method based on simulated annealing strategy is first used to generate the initial structure. Then a hybrid algorithm based on genetic algorithm and simulated annealing algorithm is used...
In order to solve the uncertainty problem of parameter variations and load disturbance which effect on the system performance, a nonlinear decoupling control based on disturbance suppression is presented for the induction motors drive system. The method combine adaptive control with nonlinear decoupling control, and the parameter variations and load disturbance are disturbance input. The state feedback...
Aerodrome control simulation system is on the support of virtual reality environment with the sense of high reality and immersion to simulate the air traffic control in the aerodrome tower. Virtual reality technology, distributed real-time computing, ATC control and information processing technology are integrated in the system. Multi-channel display system is realized to simulate the 360 degree whole...
PID controller has the problems of inferior dynamic quality and bad anti-interference ability. However, variable structure controller has the disadvantages of chattering and big steady-state error. A new controller combines variable structure and PID control method for brushless DC motor (BLDCM) of magnetic suspended reaction flywheel (MSRW) is designed. It is based on analyzing of the MSRW system...
An improved laser-controlled land leveling system is discussed with the purpose of designing the system effectively and low-cost. The system is composed of three parts. A laser emitter can produce slopes. A laser receiver can receive the laser beam and filter the noisy light, and its incepting diameter is extended to about 400 m. A controller can process the altitude signals and control the hydraulic...
