Abstract
New design method for digital servo systems with number limited and bounded inputs is proposed. Most important point in this paper is a new approach for on-line digital control algorithm for control system with bounded inputs. Bounded input is usually encountered by saturation of the actuator ability. The method is based on the already proposed "Error System Method" which has been applied for the design of the usual servo control system without bounded inputs. After transforming the original state equation of controlled object into the extended system which is called error system and defining a modified quadratic performance index so that on-line control will be possible, Maximum Principle is applied at each sampling period. Actuator is controlled by on-off command to obtain the maximum capacity of the actuator.
