چکیده
| Controlling a complex dynamic system, such as a plane or a crane, usually requires a skilled operator. Such a control skill is typically hard to reconstruct through introspection. Therefore an attractive approach to the reconstruction of control skill involves machine learning from operators' control traces, also known as behavioural cloning. In the most common approach to behavioural cloning, a controller is induced as a direct mapping from system states to actions. Unfortunately, such controllers usually suuer from lack of robustness and lack typical elements of human control strategies, such as subgoals and substages of the control plan. In this paper we apply the GoldHorn program to induce from the operator's trajectories a set of symbolic constraints. These are then used together with locally weighted regression model to determine the next action. Using the acrobot problem in a case study, this approach showed sig-niicant improvements both in terms of control performance and transparency of induced clones.

In the standard linear time-invariant multi-input/multioutput unity-feedback system, a parameterization of stabilizing controllers with integral action is obtained. These controllers guarantee asymptotic tracking of step reference inputs at each output channel with zero steady-state error.
متن کاملSome remarks on static-feedback linearization for time-varying systems
This work summarizes some results about static state feedback linearization for time-varying systems. Three different necessary and sufficient conditions are stated in this paper. The first condition is the one by [Sluis, W. M. (1993). A necessary condition for dynamic feedback linearization. Systems & Control Letters, 21, 277–283]. The second and the third are the generalizations of known resu...
