Patent ID: 7783368

Claim:
A control system controlling an output signal produced by a controlled object, the control system having a bandwidth and represented by a first mathematic model having a first transfer function, the control system comprising: a master control unit represented by a second mathematic model having a second transfer function configured to make an open loop bandwidth of the control system approach to a target bandwidth and generate a first operating signal; a first adjusting unit represented by a third mathematic model having a third transfer function and configured to receive the first operating signal and generate a first adjusting signal, wherein the first adjusting signal, the output signal, and the first operating signal are calculated for generating a second operating signal, and the output signal approaches to the first adjusting signal, so that an interference signal the controlled object subjects is offset; and a second adjusting unit represented by a fourth mathematic model having a fourth transfer function and configured to receive an input signal for generating a second adjusting signal, wherein the second adjusting signal, the output signal and the input signal are calculated for generating a third operating signal, which is provided for the master control unit and causes the first transfer function of the control system approaching to the fourth transfer function of the second adjusting unit.
