This is a book for those operating and studying biological wastewater treatment plants. It
introduces the state-of-the-art in process systems analysis (modelling and simulation …

The control parameterization method is a popular numerical technique for solving optimal
control problems. The main idea of control parameterization is to discretize the control space …

One of the most important methods in dealing with the optimization of large, complex
systems is that of hierarchical decomposition. The idea is to reduce the overall complex …

We investigate a mathematical model of tumor–immune interactions with chemotherapy, and
strategies for optimally administering treatment. In this paper we analyze the dynamics of …

We consider an optimal control problem with a nonlinear continuous inequality constraint.
Both the state and the control are allowed to appear explicitly in this constraint. By …

An efficient algorithm, called the time-optimal switching (TOS) algorithm, is proposed for the
time-optimal switching control of nonlinear systems with a single control input. The problem …

In recent years significant applications of systems and control theory have been witnessed in
diversed areas such as physical sciences, social sciences, engineering, management and …

In this paper a novel problem transformation called the Control Parametrization Enhancing
Transform (CPET) is introduced to provide a computationally simple and numerically …

Abstract Usually, an UAV (Unmanned Aerial Vehicle) path planning problem can be
modeled as a nonlinear optimal control problem with non-convex constraints in practical …

In this paper, we consider a class of optimal discrete-valued control problems. Since the
range set of the control function is a discrete set and hence not convex. These problems are …
