Abstract
Disclosed is an optimal arbitrary time-delay (OAT) filter to shape input signals by which a controlled motion is actuated in a physical system. The filter minimizes unwanted dynamics from being created by the actuation of the controlled movement in the physical system. The filter generally comprises three coefficients which are multiplied by the discrete samples of the input signal in a digital filter performing a convolution function. The samples multiplied by the three coefficients are separated by an arbitrary time delay. In this manner, three separate signals are generated. The results of these multiplication operations are summed in real time, thereby generating a filtered input signal which is sent to actuate the controlled motion of the physical system with minimal unwanted dynamics.
