Abstract It has been proposed the design method of the two-degree-of-freedom (TDOF) controller which use the dynamical model of the feedback controller. In this study, we apply this design method to the sampled-data control system. The TDOF controller is obtained so that the output of the TDOF system follows the output of the model transfer function considering the intersample behaviors.

Sample Rate

For sampled-data control systems, where a continuous-time plant is under digital control, one of the most important design parameter is the sample rate/period. Higher sample rate typically is associated with the need of high performance components and processors that results in higher system cost. In this paper, we propose an approach to determine the slowest sample rate for a sampled-data control system that will achieve the desired performance and robustness specifications. An optimization problem can be formulated using lifting technique to parameterize sample period for a sampled-data control system. The utility of the proposed approach is numerically verified through the control systems design of the media advance system of an inkjet printer.

Sampled Data Control

A discrete sequence approach is presented in this paper for investigating the possible modes of sampled-data control systems containing a saturating element. This method enables the investigator (a) to determine whether or not a control system has certain periodic modes, and (b) if it does, to identify them exactly. This approach is applicable to a sampled-data control system of any order. It is extended to the cases where the form of feedback is other than unity.
