Minimax Design of Robust Controllers for Flexible Systems Authors Singh T. Source Journal of Guidance, Control and Dynamics, 25(5), 868-875, 2002. Abstract
The design of robust time-delay and saturating controllers based on the range
of expected variation of uncertain parameters from their nominal values is
investigated. A minimax optimization problem is formulated with the
objective of minimizing the maximum value of the cost function over the range
of the uncertain parameter. By the adoption of the residual energy as the cost
function, the optimization problem formulation is simple because
it requires only one equation that is used both as the cost function and
constraint. To expedite the optimization process, equations are derived for
the gradient of the cost and constraint functions with respect to the
parameters of the controller. The proposed technique is illustrated on two
examples. The first is a spring mass dashpot and the second is the two-mass
spring benchmark problem.
