abstract = "Two genetic programming-based approaches are proposed
for continuous-time process control design. The first
approach uses a network of interconnected
continuous-time elementary dynamic building blocs with
a specific table-based representation of individuals.
In the second approach the control algorithm is
represented as a recurrent function of discrete-time
variables with the tree representation of individuals.
Both approaches are demonstrated on controller design
examples, which are compared with the genetic
algorithm-based PID controller design.",
