In the circulating water waste heat recovery system, when heat pump heating net water outlet temperature trace heating load demand, that's not only adjusted by driven steam capacity, and is easily influenced by operating conditions variation of the heating net backwater and circulating water, the traditional PID control method has a large overshoot volume and a poor load tracking ability. So a chaotic particle clone selection(CPCS)- radial basis function(RBF) direct multi-step predictive control strategy wa...
