Controlling a multi-mass system is a common problem in industrial automation, and cascaded PI controllers are a popular control structure for these systems. However, the parameters of a multi-mass system are often uncertain or can change. A robust Hinfin-control is a powerful tool in order to control systems with varying parameters. Unfortunately, the complex structure and the mathematical theory...
PI cascade controllers are often used in control applications due to their simplicity. Because of uncertain and varying system parameters, a robust control is needed. However, known methods to generate robust controllers often lead to complicated control structures. Unfortunately, there are no analytical solutions to generate robust controllers with a fixed simple structure like the PI cascade. Therefore,...
Robust control is an intensively studied field in control theory where analytical solutions for robust control problems often lead to complicated control structures. On the other hand, for simple structures like the PI cascade control l here are no analytical solutions which leads to the need of easy-to-use optimization algorithms. Differential evolution and particle swarm optimization are well suited...
