Abstract
This paper presents Dual-Rate High-Order Holds (DR-HOH) based on primitive functions, where conventional DR-HOH, such as DR-ZOH, DR-FOH and DR-SOH, are obtained using a zero, first and second order interpolation functions, respectively. Similarly, holds based on Bezier approximation functions are also obtained. They are used for signal estimation at high-frequency sampling rate from low-frequency input values. DR-HOH are validated through simulations by applying them to trajectory extrapolation in mobile robots.
