In order to improve the steady-state control performance of variable cycle engine, a steady-state multivariable control method based on LQG/LTR is proposed in this paper. The working characteristics and control laws of variable cycle engine are analyzed, and the linearized model of engine design point is obtained by system identification. Based on the LQG/LTR control method and the linear model, a multivariable steady-state controller for the variable cycle engine is designed. Through simulation verification and comparison with the control performance of the three-loop univariate PI controller, it is concluded that the multivariable LQG/LTR controller has excellent disturbance suppression and command tracking ability, and has a wider application range and better control effect than PI controller.

“…During the afterburning of additional fuel oil, the temperature of exhaust gases at the inlet to the EGB increases, which increases the temperature and pressure of superheated steam generated in the EGB as well as its flow rate in order to increase the capacity of the RTG [12]. A study by Shimanov, A.A. et al showed that afterburning is especially effective using low-power CPPs [13]. For CPPs based on gas turbine units, which correspond to a sufficiently high steam temperature, an increase in efficiency during afterburning of 8% can be observed.…”

Cogeneration or combined heat and power (CHP) has found wide application in various industries because it very effectively meets the growing demand for electricity, steam, hot water, and also has a number of operational, environmental, economic advantages over traditional electrical and thermal systems. Experimental and theoretical investigations of the afterburning of fuel oil in the combustion engine exhaust gas at the boiler inlet were carried out in order to enhance the efficiency of cogeneration power plants; this was achieved by increasing the boiler steam capacity, resulting in reduced production of waste heat and exhaust emissions. The afterburning of fuel oil in the exhaust gas of diesel engines is possible due to a high the excess air ratio (three to four). Based on the experimental data of the low-temperature corrosion of the gas boiler condensing heat exchange surfaces, the admissible values of corrosion rate and the lowest exhaust gas temperature which provide deep exhaust gas heat utilization and high efficiency of the exhaust gas boiler were obtained. The use of WFE and afterburning fuel oil provides an increase in efficiency and power of the CPPs based on diesel engines of up to 5% due to a decrease in the exhaust gas temperature at the outlet of the EGB from 150 °C to 90 °C and waste heat, accordingly. The application of efficient environmentally friendly exhaust gas boilers with low-temperature condensing surfaces can be considered a new and prosperous trend in diesel engine exhaust gas heat utilization through the afterburning of fuel oil and in CPPs as a whole.
