Design of Closed-Loop Input Shaping Controllers

Input Shaping/Time Delay Prefilter are techniques for robust vibration control of slewing flexible structures. These are open-loop schemes and cannot handle uncertain initial conditions and effects of disturbances. In this paper, we develop a technique for the design of closed loop input shapers and illustrate it on a simple benchmark problem. Range of uncertainties over which the system remain...

DC servomechanism parameter identification: a Closed Loop Input Error approach.

This paper presents a Closed Loop Input Error (CLIE) approach for on-line parametric estimation of a continuous-time model of a DC servomechanism functioning in closed loop. A standard Proportional Derivative (PD) position controller stabilizes the loop without requiring knowledge on the servomechanism parameters. The analysis of the identification algorithm takes into account the control law e...

A Receding Horizon Approach to Input Design for Closed Loop Identification

The Identification of high fidelity models is a critical element in the implementation of high performance model predictive control (MPC) applications in the industry. These controllers are large in size with input-ouput dimensions ranging from 5×10 to 50×100. Identifying models of this scale accurately is a time consuming and demanding exercise. In this work, we present a novel approach wherei...

Closed-Loop PARSIMonious Subspace Identification: Theory and Application to MPC

We propose in this paper a novel subspace identification method, based on PARSIMonious parameterization (Qin et al., 2005), and we show that such algorithm guarantees consistent estimates of the Markov parameters with open-loop and closed-loop data. The method uses the predictor form and it effectively exploits in all steps the Toeplitz structure of the Markov parameters’ matrices. After evalua...
