Space-based telescopes always have a deformable segmented primary mirror and a deformable MEMS mirror. Hierarchical control architecture is established for a space-based telescope with multiple wave-front correctors. The hierarchical control architecture organized the whole optical system as five levels, that is, object level, actuator level, local control(More)
The layout of the shape actuators in the Primary Mirror segments for a space-based telescope is a crucial factor of the adaptive control system scheme, which determines the correction capability to eliminate the face-shape error caused by the environmental temperature fields and so on. The layout design of the actuators is converted to an optimization(More)
This paper proposed a new intelligent controller for a spin missile with uncertainty and unknown parameter. The spin missile controller expression with undetermined parameters can be acquired by using adaptive backstepping design idea, and the controller parameters are optimized online by using genetic algorithm. By using this new method proposed in this(More)
An improved adaptive backstepping controller design method is proposed for a single input and single output nonlinear system with uncertainty and unknown parameter. The controller expression with undetermined parameters can be acquired by using adaptive backstepping design idea, and the controller parameters are optimized on using the adaptive particle(More)
This paper investigates the means to design a robust nonlinear controller for a class of nonlinear system with uncertainty and unknown parameter. A new design approach of optimization controller is proposed. The controller expression with undetermined parameters can be acquired by using adaptive backstepping and slide mode design idea, and the controller(More)
