Title Computing and Analysis of Control System of Guided Projectile based on Matlab
Abstract
The guided projectile has features such as a high hit rate, a high ratio of efficiency to costs and so on. The search of it’s technique has become a direction in the area of ordnance science. By searching of the guided projectile control law, we can analyze and design the control system according to requirement. In this way, the performance and accuracy of guidance can be improved. After analyzing the force and moment of projectile, the dynamic equation is established. By using the tiny disturbing arithmetic, the differential equation realizes linearization and gets the perturbation equations. To describe the dynamic performance in time domain, we can combine it with Matlab. Furthermore, the optimum control parameters can be got with the help of simulation. The results of simulation show that getting the optimum control parameters under the constraint of performance index can be realized.
