Algebraic Design Methods

Synopsis:

The course offers an alternative design method for linear control systems. The method is based on transfer functions, expressed in fractional form. All controllers are parametrized that stabilize a given plant. The optional parameter appears linearly in all closed-loop transfer functions. Additional design requirements, like those of optimality or robustness, can be achieved by a suitable choice of the parameter. Development of modern reliable algorithms makes it possible to extend the applicability of these methods in last years.
