【 摘 要 】

Solar array simulators are nonlinear control systems designed to reproduce static and dynamic characteristics of solar array. Solar array characteristics depend on illumination, temperature, space environment and other causes. During on-earth testing of spacecraft power systems there is a problem reaching stable work of simulator with different impedance loads in wide range load regulation. In the article authors propose a research method for absolute process stability in solar array simulators and present results of absolute stability research for solar array simulator with continuous parallel type power amplifier.
