   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="en_US">This thesis develops a general model for the problem of controlling a ball on a curved beam for any beam defined by y = f(x).   The model is converted to dimensionless parameters and simulated.  The performance of LQR with a model for the motor in the controls lab at the University of Maryland College Park is studied and a different nonlinear control method is investigated.   The effects of feedback delay and increased sampling interval are studied.</dim:field>
