Abstract: This disclosure presents methods and systems of controlling a counter flow double pipe heat exchanger (DPHE) that includes a hot fluid pipe and a cold fluid pipe. In a method, a temperature error between a reference temperature and a temperature at an outlet of the hot fluid pipe of the counter flow DPHE is determined. A cold fluid mass flow rate is determined from an output of a proportional-integral-derivative (PID) controller based on the temperature error being input to the PID controller. The cold fluid mass flow rate is used for a cold fluid in the cold fluid pipe of the counter flow DPHE. The temperature error is controlled within a predefined range by utilizing parameters of the PID controller that are set by using a harmony search algorithm (HSA) to obtain a minimization of a cost function.

Abstract: A measurement method for the impedance of the converter at multiple operating points based on the secondary-side disturbance includes the following steps: superimposing the positive sequence current disturbance in the current sampling value; superimposing the positive sequence voltage disturbance in the voltage sampling value; determining whether measurement data of the converter at two or more current operating points are obtained, if so, based on the measurement data of the converter at two current operating points, calculating values of A(s) and B(s); further calculating values of coefficients at each frequency point, and obtaining the impedance value of the converter at multiple current operating points by calculation. The above-mentioned measurement method overcomes the disadvantages of high cost and complicated operation of the impedance measurement method based on the primary-side disturbance, and solves the problem of lacking the pre-judgment function.

Abstract: A pure-rolling generating measurement method and device for gear helix artifact is proposed, which use a dividing table to accurately control the linear rail slide block assembly component to rotate according to the helix angle of different base circle. The height of the measuring point is the installation height of the working plane of generating rails, so as to ensure that the measuring point is always located on the dividing cylindrical surface of the gear helix artifact. When the gear helix artifact does pure-rolling motion, the slide block performs high-precision linear motion on the working surface of two fixed rails; the pure-rolling motion is proportional to the high-precision linear motion, so that the inductor micro-displacement probe can complete the measurement of the helix deviations of the gear helix artifact with different base circle helix angle.
