Function generator for producing a triangular waveform having only positive peak values

Abstract

Abstract A RAPID PROCESS SIMULATOR FOR DETERMINING BOTH STATIC AND THE DYNAMIC CHARACTERISTICS WHICH ARE UNKNOWN IN A RELATIVELY STABLE PROCESS. THE SIMULTOR INCLUDES A PULSE GENERATOR FOR PRODUCING A PERTURBATING PULSE WHICH IS APPLIED TO THE PROCESS. THE PERTURBATING PULSE PRODUCES AN OUTPUT SIGNAL WHICH CAN BE EXPRESSED IN THE FORM OF A POLYNOMIAL. THE PROCESS IS COMPARED IN THE SIMULTOR WITH AS MODEL OF ORTHOGONAL FUNCTIONS WHICH ARE CAPABLE OF BEING NORMALIZED TO AN ORTHONORMAL CONDITION. THE MODEL IS FORMULATED WITH THE IDEA OF CHOOSING A PULSE INPUT IN SUCH A WAY AS TO FACILITATE THE CONSTRUCTION OF THE SYSTEM. AN OUTPUT SIGNAL IS ALSO PRODUCED IN THE MODEL WHICH IS IN TURN COMPARED WITH THE OUTPUT SIGNAL FROM THE PROCESS IN ORDER TO ACHIEVE AN ERROR SIGNAL. THIS SIGNAL IS SQUARED IN THE SIMULATOR AND INTEGRATED TO DETERMINE THE CHARACTERISTICS OF THE SYSTEM. THE SIMULATOR INCLUDES A TRANSPORT DELAY DEVICE FOR DELAYING THE PERTURBATING PULSE TO THE MODEL WITH RESPECT TO THE PROCESS, SO THAT THE OUTPUT OF THE PROCESS AND THE MODEL WILL BEGIN IN COINCIDENT TIMES. IN ADDITION, THE SIMULATOR IS PROVIDED WITH A GENERATOR TO PRODUCE OSCILLATORY TRANSIENTS ON A MODEL OF THE SIGNAL TO MATCH TRANSIENT ON THE PROCESS SIGNAL.
