Abstract:

We developed two linear parameter insensitive controllers, one based on a periodic function of state variables and the other on a linear combination of past states and inputs. Leads and lags used in classical control laws are also special cases of the parameter insensitive controllers suggested by us in the paper. Parameter insensitive controllers and filters presented in this paper extend the structure of controllers for completely known systems to partially known systems in a logical manner. The advantages of our controllers are a they are simple to design and implement, b a desired tradeoff may be made between optimality and complexity, c the stability properties and stability regions are easily determined, d the structure of the controller does not change as long as the parameters vary within the prescribed set, and e the controller works well when parameters change relatively fast. A disadvantage is that there is no learning.
