Internal Model Control Revisited
Abstract
By the Internal Model Principle, robust asymptotic rejection of persistent exogenous signals with known patterns (constant, harmonic, periodic) requires incorporating their models (integrator, harmonic oscillator, repetitive element) into the feedback loop. A conventional design approach in this case is to augment the plant by the dynamics of the model and to design a stabilizer for the resulted augmented system. An obvious disadvantage here is an increase of dimensions, which is especially troublesome for infinite-dimensional models, like those arising in repetitive control.
In this talk an alternative approach will be presented, in which special dynamic elements are added to the loop to compensate for the addition of the internal model in stabilization tasks. Those elements are, in a sense, dual to the celebrated dead-time compensators and are thus termed \emph{CIM elements} (compensators of internal model). With the use of CIM elements the stabilization of the augmented plant becomes equivalent to that of a plant having the same dimension and zero structure as the original plant itself.
The talk is based on a joint work with Patrizio Colaneri and Gian Paolo Incremona from Politecnico di Milano.
Short Bio
Leonid Mirkin is a native of Frunze, Kirghiz SSR, USSR (now Bishkek, Kyrgyz Republic). He received the Electrical Engineer degree from Frunze Polytechnic Institute and the PhD (candidate of sciences) degree in automatic control from the Institute of Automation, Academy of Sciences of Kyrgyz Republic, in 1989 and 1992, respectively. He joined the Faculty of Mechanical Engineering at the Technion - Israel Institute of Technology in 1994, first as a postdoc and then as a faculty. His research interests include systems theory, control and estimation of sampled-data systems, dead-time compensation, systems with preview, distributed control, and applications in electro-mechanical systems and process control.
