Estimating the term…
A regulator or engine regulator having two regulator channels (20, 20′) which each have at least two processor units (22, 24 or 22′, 24′, respectively) is developed in that in each case one processor unit (for example 22, 22′) operates as a calculation unit for each safety-critical function in both regulator channels (20, 20′), in order to determine calculation results from at least some of the input data (E, E′), and in each case one other processor unit (for example 24, 24′) operates as a monitoring unit in order to compare the calculation results from the calculation unit firstly with its own estimate of the correct results and secondly with corresponding results from the respective other regulator channel (20′, 20). An engine and method for regulating an actuating or propulsion system, or an engine, have corresponding features. The invention improves the operational safety in particular of a two-channel regulator or an engine regulator with little complexity, and, in particular, allows reliable identification of malfunctions in one channel.
