Contrary to the problem of plateau acute reaction caused by the low oxygen partial pressure, we designed a simulated altitude environment atmospheric hypoxia chamber. The control system is based on fuzzy adaptive algorithm combined with expert algorithm and PD algorithm, which can justify parameter itself to fit the environment of time-delay and instability. During 10 days of hypoxic training, the...
The key equipment of photovoltaic grid-connected system is photovoltaic grid-connected inverter; the output power quality is determined by the control method of inverter. Based on the model of a photovoltaic grid-connected inverter, this paper presents a new grid-connected inverter control algorithm that is iterative proportional integral algorithm, and derives an output expression and transfer function...
A new design method of stability control loop for the swing nozzle thrust control anti-air missile is present in this paper. Firstly, the model of the missile which considered the aeroservoelastic and swing nozzle effect is given. Then, based on the small error linearization model, the theory of Variable Structure Control is used for stability control loop design for the missile with the model uncertainty...
The PID (proportional, integral, differential) control method is widely applied to missile attitude control. The usual empirical method for optimizing the three control parameters of Kp, Ki and Kd can not optimize them on line and in real time. The paper presents the PID parameter optimization method that uses RBF neural network, applies it to a missile's longitudinal control system parameter optimization...
A new design method of autopilot for the anti-air missile with swing nozzle thrust control is present in this paper. Firstly, the model of the missile which considered the aeroservoelastic is given. Then, the autopilot is designed using the theory of mu-synthesis for the missile containing the model uncertainty and disturbance, the framework of the mu-synthesis of the longitude autopilot is constructed...
Proportion integral differential (PID) control is widely used for missile control systems, but it is difficult to achieve parameter optimization because the three control parameters Kp, Ki, Kd are empirically selected. Genetic algorithm is a search algorithm that is based on natural selection and genetics principles and randomly generates the initial population of the PID control parameters according...
A switch scheme of reaction-jet/aerodynamic multi-control missile using pose controlled pulse-engine is present. In order to increase response speed of autopilot and reducing the coupling form Reaction-jet to aerohelm, in the last stage of attacking the aerodynamic controller is disconnection and Reaction-jet controller is used only. In the first part, the model of the Reaction-jet control system...
