چکیده

In this paper, we develop a hybrid iterative learning controller (HILC) for non-holonomic wheeled mobile platform to achieve trajectory tracking with actual complex constraints, such as physical uncertain parameters, and initial errors. Unlike the traditional (ILC), control variable selects rotation speed of two driving wheels instead forward speed. The considers constraints robot’s motors can effectively handle parameters errors system. Without errors, improve convergence by adding other types error signals; otherwise, achieves designing signal compensation Then, effectiveness proposed is proven relationship between input, output, status signals. Finally, simulations demonstrate that tracked various trajectories directly controlling under constraints. Furthermore, results show did not significantly depend on system’s structural parameters.

Iterative Learning Controller Design for Multivariable Systems

In this paper, a novel expression for the convergence of an iterative learning control algorithm for sampled linear multivariable systems is stated. The convergence analysis shows that, applying this algorithm, the input sequence converges to the system output inverse sequence, specified as a finite-time output trajectory, with zero tracking error on all the sampled points. Also, it gives insig...

Robust Iterative Learning Controller Design for 2d Uncertain Linear Systems Subject to External Disturbances

This paper presents a robust iterative learning control (ILC) for a class of two dimensional (2D) linear systems with parametric uncertainty and considerable disturbances. The proposed control law is iteratively updated to guarantees the robust stability. Based on H∞ setting, sufficient conditions for robust monotonic convergence of the proposed scheme are presented in terms of linear matrix in...

An iterative learning controller with initial state learning

In iterative learning control (ILC), a common assumption is that the initial states in each repetitive operation should be inside a given ball centered at the desired initial states which may be unknown. This assumption is critical to the stability analysis, and the size of the ball will directly affect the final output trajectory tracking errors. In this paper, this assumption is removed by us...
