摘要
基于模糊技术和PID技术对钒基储氢合金V3TiNi0.56Cr0.2的熔炼温度和浇注温度进行了智能PID控制,并与常规PID控制进行了对比。结果表明,智能PID控制有助于提高合金的电化学腐蚀性能和电化学循环稳定性。与常规PID控制相比,智能PID控制使合金的腐蚀电位从-0.914V正移到-0.836V,正移了78mV,充放电循环20次后的放电容量衰减率从78%减小至46%。
The melting temperature and pouring temperature of vanadium-based hydrogen storage alloy V3TiNi0.56Cr0.2 were controlled by intelligent PID based on fuzzy technology and PID technology,and it was compared with that by conventional PID control.The results show that the intelligent PID control is helpful to improve the electrochemical performance and electrochemical cycling stability of the alloy.Compared with that by conventional PID control,the corrosion potential of the alloy by intelligent PID control is shifted from -0.914V to -0.836V,and the positive shift is 78 mV,and the reduction rate of discharge capacity is decreased from 78% to 46% after 20 cycles of charge-discharge cycle.
