The semantic model of the real-time control algorithms introduced by the author in the previous papers deals with the quads representing execution of the particular functional task at settled time. The important element of the quad is duration of the task. The formal system of the real-time control algorithms is used in collaboration with the semantic model as the language for specification and verification...
This paper presents a fuzzy feedback control system for DC voltage regulation of a phase-controlled three-phase rectifier. The controller operating range covers both the continuous conduction mode and the discontinuous conduction mode. In the latter operating region, the converter characteristics are highly nonlinear and too difficult to be modeled mathematically. For this reason, a fuzzy control...
This paper describes a mechatronic system for a model ship that is developed as a validation platform for ship maneuvering control system research. The model ship is a free-running system that is propelled and steered by two propulsion motors and two rudder motors, respectively, powered by batteries packed onboard. Real-time control is performed by an embedded processor, with control algorithm being...
This paper presents a novel approach for wireless networked real-time control. Using delta-sigma modulation sensing and control signals are encoded in a binary format, which can be implemented in one-bit registers. The one bit signals are pulses that are able to be transmitted naturally in wireless. Control laws can be efficiently implemented with one-bit signals at both the input and output. The...
Since job shop production procedure diverts always from original scheduling plan, it is essential to renew the plan for delivery time. An automatic control theory is presented, whose principles include sampling, identification and calculation. The information of the deviation from original scheduling plan is sampled as production state, and original scheduling order is resumed to insure their delivery...
