| Abstract_FL | This paper considers the multi-objective safe control problem of input-affine nonlinear systems subject to the constraints on the state and control.A new multi-objective safe model predictive control(MOSMPC)scheme is proposed for the system with guaranteed safety and stability.First,the utopia-point approximation method is adopted to solve the conflicting problem of multiple control objectives.Second,the control Lyapunov-barrier function(CLBF)is used to parameterize the local control laws of the system and determine the unsafe domains of the system.Then the parameterized dual-mode controller of the nonlinear system is constructed to reduce the computational amount of online solving the MPC optimization problem.Moreover,recursive feasibility of the MOSMPC scheme and asymptotic stability of the closed-loop system are established via the dual-mode control principle and the CLBF constraint,which ensures that the states of the closed-loop system can avoid the unsafe domain.Finally,an example of multi-objective control of a heating system is used to verify the effectiveness of the proposed strategy. |
