Pseudolinearization of the Acrobot using Spline Functions

by Scott A. Bortoff and Mark W. Spong


Abstract: This paper presents a technique for the construction of an approximation to the nonlinear control that pseudolinearizes a single-input nonlinear system. The construction is computer automated and yields a computationally inexpensive controller, regardless of the complexity of the original nonlinear system. Experimental results obtained by implementing the approximate pseudolinearizing control law on a remotely driven acrobot verify the controller's ease of design and computational efficiency.
