A State Space Average Model for Dynamic Microgrid Based Space Station Simulations

In this paper a state-space average model for boost switching regulators is presented. The presented model includes the most of the regulator’s parameters and uncertainties. This model can be used to design a precise and robust controller that can satisfy stability and performance conditions. In modeling, the load current is assumed to be unknown, and it is assumed that the inductor, capacitor, diode and regulator active switch are non ideal and they have a resistance in conducting condition. Other non ideal effects are also considered. After presenting the complete model, the boost converter Benchmark circuit is simulated in PSpice and its results are compared with our model simulation results in MATLAB.

Abstract Many microgravity space-science experiments require vibratory acceleration levels unachievable without active isolation. The Boeing Corporation’s Active Rack Isolation System (ARIS) employs a novel combination of magnetic actuation and mechanical linkages, to address these isolation requirements on the International Space Station (ISS). ARIS provides isolation at the rack (International Standard Payload Rack, or ISPR) level. Effective model-based vibration isolation requires (1) an appropriate isolation device, (2) an adequate dynamic (i.e., mathematical) model of that isolator, and (3) a suitable, corresponding controller. ARIS provides the ISS response to the first requirement. This paper presents one response to the second, in a state-space framework intended to facilitate an optimal-controls approach to the third. The authors use “Kane’s Dynamics” to develop an state-space, analytical (algebraic) set of linearized equations of motion for ARIS.
