Input shaping, a technique for reducing residual vibration, was evaluated for use with trajectory following applications. The performance of input shaping for trajectory following was investigated by simulating the response of a two-dimensional system with orthogonal modes. Due to the difficulty of predicting the response of a flexible system to an arbitrary trajectory command, the investigatio...

This paper presents an approach using a multi-objective controller to prevent noise and vibration generated by the wiper blade during its wiping operation. Firstly, this paper focuses on the experimental approach to collect noise and vibration data from a car wiper system during its operation and secondly, to develop black box model of the wiper system using nonparametric approach of system ide...

Orthogonal eigenstructure control is a novel control method that recently has been developed by the authors as a method for active vibration cancellation. This method is a feedback control method, which is applicable to linear multi-input multi-output systems. The remarkable advantage of this method over most of the eigenstructure assignment methods is that it neither needs pole placement nor e...

In this paper we propose a systematic methodology that integrates the three main phases of the design of an industrial control system, namely, the identification phase, the tuning of the (PID) controller and the design of a (noncausal) feedforward action. In particular, the tuning of the controller is based on frequency loop shaping where the modelling uncertainty is explicitly considered and t...

Systems that exhibit flexible dynamics are susceptible to vibration caused by changes in the reference command and from external disturbances. Feedback control is an obvious choice to deal with these vibrations, but in many cases, it is insufficient or difficult to implement. Input shaping does not deal with vibration excited by external disturbances; however it has proven beneficial for reduci...

Precise manipulation of payloads is difficult with cranes. Oscillation can be induced into the lightly damped system by motion of the bridge or trolley, or from environmental disturbances. To address both sources of oscillation, a combined feedback and input shaping controller is developed. The controller is comprised of three distinct modules. A feedback module detects and compensates for posi...

Application of flexible structures has been significantly, increased in industry and aerospace missions due to their contributions and unique advantages over the rigid counterparts. In this paper, vibration analysis of a flexible structure i.e., automobile wiper blade is investigated and controlled. The wiper generates unwanted noise and vibration during the wiping the rain and other particles ...
