1. the 3PTT-2R serial-parallel NC machine tool servosystem fault prediction device based on residual error observer, it is characterized in that, the device carrying out failure predication for 3PTT-2R serial-parallel NC machine tool servosystem includes 3PTT-2R serial-parallel NC machine tool kinetic model module (1), residual error observer module (2), the Strong tracking filter module (3) improved and failure predication module (4);

  • The status signals such as the rotating speed that 3PTT-2R serial-parallel NC machine tool kinetic simulation module (1) exports according to controller build serial-parallel NC machine tool kinetic model, and according to kinetic model by speed, the signals such as displacement are operated output, residual error observer module (2) receives the status signals such as the rotating speed of the status signals such as the actual speed of Series-parallel Machine kinetic model output and controller output simultaneously, the residual error of the state variables such as residual error observer module (2) output Series-parallel Machine rotating speed gives the Strong tracking filter module (3) improved, the improved residual signals after Strong tracking filter module (3) Filtering Processing exports to failure predication module (4), residual error is output fail result after failure predication module (4) processes.
