This article focuses on the spacecraft attitude control problem involving angular velocity limitation and performance requirement, while the parameter uncertainty issue is considered simultaneously. To address this problem, we propose a modified control scheme called compatible performance control (CPC), which integrates the prescribed PC (PPC) scheme with a constraint contradiction detection and performance envelope modification strategy. First, by leveraging the concept of the zeroing barrier function, we propose a detection strategy to assess whether the preassigned performance envelope is reasonable or not, providing judgment on the compatibility between the velocity limitation constraint and the predefined performance function envelope constraint derived by PPC control. Subsequently, a performance envelope modification strategy designed based on the $\Gamma$-projection operator technique is presented, which generates a modification signal for the predefined envelope if a contradiction is detected. Meanwhile, in order to satisfy the angular velocity limitation, a filter technique is introduced to generate a bounded virtual control signal. Furthermore, we employ a time-varying gain adaptive technique to address the challenge of parameter uncertainties, providing the system with robustness and disturbance rejection capability. We then construct an adaptive CPC controller, which guarantees the ultimate boundedness of the system while all constraints are satisfied simultaneously. Finally, numerical simulation results are presented to show the superiority of the proposed framework.
