Roots-type engine is suitable for small power generation system fuelled by
waste heat. The disorderly fluctuations of the waste heat source upstream of
the power generation process and changes in external environmental factors
cause the working parameters of the device to change, which makes the speed
of roots engine unstable, and the output power quality of the system is not
good. For this problem, this paper starts from the control structure and
control strategy to improve the adjustment speed and anti-interference
ability of the control system. In this contribution, the model
transformation of the dynamic work unit of waste heat power generation
device from engineering to theoretical model is performed, the temperature
of working gas and the speed of output shaft of roots engine are determined
as control objects, and the internal mode control strategy is introduced to
optimize the controller of the system. Simulation results are in good
agreement with the measurements, which verify that the optimized control
system can effectively improve the following ability and anti-interference
of the system, and shorten the response time.
