THE MULTIBOUND DIGITAL REGULATOR SYNTHESIS OF THE STABILIZATION SYSTEM OF THE TECHNOLOGICAL SPACE PLATFORM

摘要

They observe in this paper the problem of active control of the of the vibration isolation platform position for realisations of space technological experiments. The principles of control of platform position concerning the basis of the load-carrying structure of a space according the signals of accelerometers and gauge of relative position make a methodical basis. The separate task includes development the principle of the work of high-resolution accelerometer. This kind of the accelerometers are intended for a measurement in conditions of microgravity of levels of vibration accelerations of the order 10"6 g. The movement of drive mechanisms between the platform and the basis ensures control of the platform position in space. The regulator treats an information from gauges and sends pilot signals to the electric drive, which one actuates an the drive mechanism. The regulator is designed as multivariable, combining analogy and digital control. Depending on an allowable level of relative movement the variable structure of a system of control is offered. The control algorithms are constructed. These algorithms combine as invariant control, which one ensures a zero level of accelerations on object, and control on feedback. The outcomes of experimental researches are indicated.
