Application of predictive position control in conjunction with a control surface

A general controller structure has been evolved for application to position control tasks in electromechanical actuating systems. The controller takes practical and functional requirements such as a minimum of adjustable controller parameters, near time-optimal performance, boundedness of actuator output into account. The structure consists of a lead filter and a nonlinear characteristic specially suited to the problem. Long term parameter changes are compensated by adapting one parameter in the lead filter. Simulation results for a benchmark problem-electromechanical actuator-which substantiate the principle employed are given
