Taking unfinished parts, that is, parts' work-in-progress (WIP), as the background, the PI control algorithm is proposed to apply for WIP control in discrete production systems and the cascade control of PI controllers is suggested. Designing of PI controllers is transformed into an optimization problem on the frequency domain, so as to guarantee the stability and robustness of PI controllers' parameters...
We have recently demonstrated in simulations and experiments that a proportional and derivative (PD) feedback controller, which uses the body kinematics to regulate the active ankle torque during quiet stance, can stabilize the body despite a long sensory-motor time delay. The purpose of the present study was to implement the PD controller in a neural-mechanical control scheme of quiet stance and...
In this paper, remove material processes are into account for developing an expert mill cutter and cutting parameters selection system based on numerical methods of performance evaluation. The knowledge base is given by limitations in process variables, which let us to define the allowable cutting parameter space. The mentioned limitations lead to instabilities due to tool-work-piece interaction,...
Overseas telecommunication is preserved by means of satellite communication. Tracking system directs the on-board antenna toward a chosen satellite while the external disturbances affect the antenna. Certain faults (beam sensor malfunction or signal blocking) cause interruption in the communication connection resulting in the loss of the tracking functionality. In this paper, an optimization based...
In this paper, an optimization method of low order multivariable controllers for Hinfin control is proposed. Starting from a low order stabilizing controller, our proposed method gives a sequence of controllers for which the Hinfin norm performance index is monotonically non-increasing where the tuning parameters are the coefficient matrices C and D of the low order controller with the matrices A...
Correct diagnosis under harsh environmental conditions is crucial for space vehiclespsila health management systems to avoid possible hazardous situations. Consequently, the diagnosis methods are required to be robust toward these conditions. Design of a parametric fault detector, where the fault estimation is formulated in the so-called standard set-up for Hinfin control design problem, is addressed...
PID control is probably the most applied control strategy around the world. There is also a huge amount of literature available about this control strategy. In the most common case, the controller is formulated in the continuous-time domain. If it is necessary to implement the controller as a computational algorithm, controllerpsilas equations are discretized. It is less frequent to find PID control...
The paper presents a method for the soot blowing optimization and its pilot application to the oil fired boiler of a power plant. The important monitored parameter of each steam generator is the thermal efficiency or the heat rate. These parameters are influenced by many factors, including for example the boiler design, control strategy, fuel quality, operating conditions, etc. The quality of the...
