The paper presents an efficient computational method for Maximum Range of guided bombs based on differential flatness. Differential flatness theory is briefly described and original motion model of guided bomb is reformulated by introducing flat outputs. The original states and inputs can be defined in terms of the flat outputs and their derivatives, and all the boundary conditions and path constraints...
Development of feasible and precise methods for calculating guided bomb's optimal trajectory has been a traditional and challenging task. The inherent difficulty arises from significant nonlinearity of trajectory model, limited control inputs and various constrained states. And most conventional direct and indirect methods are very sensitive to the initial guess that needs much experience. This paper...
A new method of the optimal sliding mode variable structure control is presented to eliminate the extraneous torque in the load simulator. The mathematical model of the load simulator is enlarged by incorporating the torque reference input with integral action. By proper state transformation, the construction of the optimal sliding surface equals to the design of the feedback matrix in the linear...
In flight control, control allocation is used to distribute the total control command to each actuator when the number of actuators exceeds the number of controlled variables. A new optimal control allocation method based on nonlinear compensation was proposed in this paper. The quadratic term and mutual-interference effects were introduced into control effectiveness matrix. The linear combination...
The optimal gliding control problem is studied for guided bombs. Optimal control theory is used to describe the characteristics of continuous variation in gliding control system for guided bombs. The optimal control model of guided bomb is built and solved using maximum principle with final state constraints and shooting method for boundary values. The shooting method is modified to meet desired performance...
