A robust control scheme for high angle of attack tracking of one class of missiles with reaction jets is presented. The control scheme contains an adaptive SMC controller and a control moment allocator. In the former, an adaptive compensator based on radial basis function neural network is used to eliminate chattering by compensating the missile disturbances and uncertainties. The latter is designed...
This paper presents a switched stabilization method of discrete interval type-2 fuzzy systems via sum-of-squares (SOS). Based on polynomial Lyapunov functions, we derive stabilization conditions to design stable polynomial interval type-2 fuzzy switched controllers. The stabilization conditions are represented in terms of SOS, and the controllers are numerically (partially symbolically) solved via...
This paper designs a fuzzy incremental hierarchical sliding mode controller for a class of under actuated systems. By capturing the physical structure of the class, the hierarchical sliding surfaces with incremental structure are designed as follows. The first-layer sliding surface is firstly defined. Then, the first-layer sliding surface and one of the left states are employed to construct the second-layer...
A new stable sliding mode control method for a class of underactuated mechanical systems with saturation is proposed in this paper. Two state variables of the underactuated system are chosen to construct the first-layer sliding surface. Then, the first-layer sliding surface and one of the left state variables are used to construct the second-layer sliding surface. This process continues till the last...
