This paper presents the extended penalty function method for solving c
onstrained optimal control problems. Here, equality and inequality con
straints on the state and control variables are considered. Using the
extended penalty function method, the original constrained optimal con
trol problem is transformed into a sequence of optimal control problem
s without inequality constraints. This is accomplished by adding to th
e cost functional a penalty term that takes on large values when the i
nequality constraints are violated and small values when the constrain
ts are satisfied. Also presented is a continuation method for solving
the sequence of differential-algebraic boundary value problems arising
from the transformed optimal control problems. The effectiveness of t
he approach is demonstrated via examples.
