Repetitive Control for an Electrostatic Microbridge Actuator
Design Engineering, Parts A and B, 2005Electrostatic microactuators are used extensively in MEMS sensors, RF switches, and microfluidic pumps. Due to high bandwidth operation, however, reduction of residual vibration using feedback control is diffcult to implement. This paper designs, proves stability, and simulates a feedforward repetitive controller for an electrostatic microbridge ...

Repetitive controller design in parameter space
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001A new and simple repetitive controller design procedure in controller parameter space, where the structure of the filters in the repetitive controller are fixed from the start and parameters within these filters are tuned, is presented here. This approach results in simple and physically meaningful controllers that are easily implementable.

Application to Repetitive Control
2009In the early 1980s, Inoue et al. [75,76] and Hara et al. [59,60] laid the foundation of repetitive control. Facing the control problem of asymptotically rejecting periodic inputs of which only the period Tp is known, they relied on the Internal Model Principle [34,45,46,47,48] and included the signal generator shown in Figure 5.1(a) in the controller ...

A survey on robust Repetitive Control and applications
2014 IEEE International Conference on Control System, Computing and Engineering (ICCSCE 2014), 2014Tracking and rejecting periodic signals are common tasks in many control applications. A well-known use of Repetitive Control (RC) is to both track a periodic reference signal and reject periodic disturbance. This paper reviews various designs of RC that are classified into basic RC design and robust RC design.

On Dead-Time Compensation in Repetitive Control
IEEE Control Systems Letters, 2020The note studies the stabilization problem for a SISO continuous-time plant, where the feedback loop contains a fixed infinite-dimensional repetitive element and a “primary controller” to be designed. A novel architecture of the primary controller is proposed, which reduces the stabilization problem to that for a finite-dimensional system.

A new repetitive controller for mechanical manipulators
Journal of Robotic Systems, 1991AbstractA new repetitive learning controller for motion control of mechanical manipulators undergoing periodic tasks is developed. This controller does not require exact knowledge of the manipulator dynamic structure or its parameters, and is computationally efficient.

Controllability and stability of repetitive batch processes
Journal of Process Control, 2007Batch control has traditionally addressed the problems related to the absence of a steady state and the finite batch duration. Recently, batch control has added the dimension that arises naturally from the possibility of applying run-to-run control, i.e. it exploits the fact that most batch process are repeated over time. Hence, batch control calls for

Movement Control in a Repetitive Motor Task
Nature, 1970IN experiments that used a pencil and graph paper targets, we have been able to demonstrate what we believe to be the intermittency of visual feedback control in a simple motor task. The intermittency hypothesis was first advanced by Craik1. It was developed by E. R. F. W. Grossman and P. J.

Stability of Higher Order Repetitive Control
2005Repetitive control (RC) and iterative learning control (ILC) apply to repeating situations, and iteratively adjust the command to a feedback control system aiming to converge on zero tracking error. Thus, these forms of control solve an inverse problem, but instead of doing so numerically with a mathematical model, it is done iteratively with the real ...

A Digital Segmented Repetitive Control Algorithm
Journal of Dynamic Systems, Measurement, and Control, 1994This paper presents the structure and analysis of the segmented discrete-time repetitive controller. The repetitive controller is designed to reject periodic disturbance and/or track periodic reference signal with known period. Resulted from the Internal Model Principle, the repetitive control law is applied to the entire control path.
