Synchronization problem was the principal problem and technological challenge for hydrostatic driving tracked vehicle in straight working conditions. The asymmetry caused by parameter perturbations, friction resistance coefficient, leakage coefficient and pump displacement are taken into consideration. These factors were treated as disturbance inputs, and were suppressed by control algorithm. A simulation...
This paper reports the design, simulation and test results of a C-band broadband klystron, which was developed by the Institute of Electronics, Chinese Academy of Sciences (IECAS) from March 2005 to June 2008. The typical result is over 800 kW peak output power and 30% conversion efficiency of beam-to-RF among a 400 MHz bandwidth under 5.250/00 RF duty cycle. The overall length of the tube is 702...
This paper reports the design considerations, simulation results and test specifications of an S-band, 70 MHz bandwidth, 50 kW average power klystron, which was developed by the Institute of Electronics, Chinese Academy of Sciences (IECAS) before August, 2007. The representative result is 56 kW average output power under the conditions of 89 mus RF pulse width, 300 Hz repetition rate, and continuous...
