| Abstract |
Position Drives are almost elastically coupled multimasse-systems with changeable parameters and changeable disturbance signals. In this contribution, simple adaptive structures are discussed, which enables a fast control of the position process undependent upon parameter changes and disturbances. The control is realised by small microcomputers. The state-space-control of the motion-process and adaptive structures using signal-selfadaption are discussed. If the range of parameter-changes is limited, a structure using signal-selfadaption enables a very good dynamic behavior of the closed loop control. A linear and a nonlinear control algorithm is used in combination. So we could combine a good dynamic behavior of the system with a good constantness of the control signal. We could make a very effective use of the motor and the power electronic converter. |
