Finite Time Prescribed Performance Control of Multi-agent Systems with Unknown Control Directions
A class of multi-strict feedback systems with multiple unknown and non-identical control directions are investigated for a prescribed performance control problem in finite time.To facili-tate the proof,the article converts the proof of the stability of the whole system into the proof of the boundedness of the subsystem errors,which simplifies the design and analysis process.In addition,the derivation of virtual control quantities in the traditional back propagation method is avoided by the com-mand filtering technique.The designed distributed controller can ensure that the neighborhood error e-volves within the specified bound and can set the convergence time arbitrarily,i.e.,converge to a prede-fined arbitrarily small neighborhood within the specified time,improving the steady-state and transient performance of the system.Finally,the effectiveness of the proposed controller is verified by a numeri-cal simulation.
