low transmission loss, low emissions, and flexibility for utilizing a variety of energy sources, including fossil fuels and renewable energy sources (RES) [3]. As a key form of DES, micro gas turbine (MGT)-based combined cooling, heating and power systems (CCHPs) have attracted much attention worldwide because of their energy-efficiency, low-emissions and operational cost-saving characteristics [4; 5; 6; 7]. Since the waste heat of the MGT can be continuously utilized as a heat source for a water heater or a cooling device, the average energy efficiency of the MGT-CCHP system can reach 80%, whereas the average thermal efficiency for a combined cycle gas turbine (CCGT) is approximately 50% [8]. In addition, compared with the traditional centralized power generation system, the MGT-CCHP system is smaller in size so that it can be flexibly installed in small residential or commercial districts. At present, the research on MGT-CCHP system mainly focuses on static system configuration [9], operation optimization [10] and performance evaluation [11]. In [9], a CCHP microgrid composed of photovoltaic cell, gas turbines, gas boiler, thermal storage tank, absorption chiller, electric chiller, as well as cooling, heating, and power load is studied. In [10], a mixed-integer linear programming model was established for the optimal design of the distributed energy resource system. In [11], the performances of CCHP system in different operation modes are compared. Although the dynamic characteristics of the MGT-CCHP system have been studied in recent years [12; 13], the control method used for the MGT-CCHP system is still the conventional PI/PID control. In order to improve the performance of the PI/PID controller, intelligent methods such as fuzzy logic [14; 15], neural network [16], firefly algorithm [17] are used to tune the parameters of the PID controller. However, due to the complex dynamic characteristics of MGT-CCHP system, such as nonlinearity, large thermal inertia, multi-variable strong couplings, unknown disturbances and so on, the single-input-single-output (SISO) PID control is no longer applicable to meet the performance requirement, even if the parameters of the PID are well tuned.
