ROCKETS STABILIZATION CONTROL SYSTEMS USING DIFFERENTIATOR OR INTEGRATOR GYROSCOPES
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2010, Vol 34, Issue 34
Abstract
The paper presents the comparison between two angular stabilization systems of the rockets in vertical plane using a differentiator or an integrator gyroscope, an accelerometer and a correction subsystem. One has determined the transfer functions (in closed loop or in open loop) of the system in the complex variable or in discrete variable. All the eigenvalues of the system are placed in the left complex semi-plane (the proof of system’s stability). For both systems one obtains, using a Matlab/Simulink program, the indicial functions in the complex plane and in discrete plane, responses to impulse input in the complex and discrete planes. The identification of the systems is made using neural networks’ method. One obtained the indicial responses of the control system and of the neural network after the training process and the dependence between the training error and the training epochs’ number.
