Abstract：Without considering actual constraints, the rationality of reconfigurability distribution and the influence caused by reliability, the existing reconfigurability evaluation methods for control systems are flawed in many aspects. To overcome these defects, a new reconfigurability evaluation method is proposed here for a kind of energy-and-time-constrained control systems. First of all, the maximal recoverable state domain is determined based on minimum energy control strategy and its reliability is optimized. Next, coordinate of the recoverable state domain is scaled according to the expected reconfiguration capacity in different directions. Then, by calculating generalized volume of the scaled domain based on precise integration method, the definition of reconfigurability degree is introduced to quantitatively describe the control systems'reconfiguration capability. What's more, the application of proposed method is elaborated respectively from system design phase and online monitoring phase. Finally, numerical simulations are employed to demonstrate the effectiveness of the proposed evaluation method and the results show that control reconfigurability is influenced by both space and time factors.
