Abstract: A multivariable version of the zero phase error tracking control algorithm is presented for sampled-data systems. The feedforward controller is based on the minimal-order inverse of a square ...

Abstract: A new method is described for estimating input time delays in linear plants. The method is based on discrete-time domain identification of such delays, and provides direct estimates in real-time. ...

Abstract: The integral-lift scaffolds are widely used in construction of tall buildings in Asia. However, the wind load on scaffolds may be much greater than dead load and be the dominant effect as the scaffolds climb over
