20090284210 | ADAPTIVE SERVO CONTROL SYSTEM AND METHOD - A system and method of implementing servomechanism control without rate feedback is provided. A position feedback signal is filtered using a non-linear lead-lag filter that has a variable frequency response to thereby generate a compensated position feedback signal. A position error signal is generated from a position command signal and a sensed position signal, and the frequency response of the non-linear lead-lag filter is varied in response to the position error signal. A compensated position error signal is generated from the commanded position signal and the compensated position feedback signal. The compensated position error signal is at least selectively filtered using a non-linear integral filter that has a variable gain to thereby at least selectively supply a filtered position error signal. The gain of the non-linear integral filter is varied in response to the compensated position error signal. | 11-19-2009 |
20100023301 | ELECTROMECHANICAL ACTUATOR AND EFFECTOR HEALTH MANAGEMENT SYSTEM AND METHOD - A system and method are provided for supplying electromechanical actuator (EMA) health status information to a control system. A determination is made as to whether the EMA has experienced a fault. If the EMA has experienced a fault, a fault-based position limit and a fault-based rate limit of the EMA are determined, based on the fault. A design position limit and a design rate limit of the EMA are supplied. An updated position limit of the EMA is determined based on at least the design position limit and the fault-based position limit, and an updated rate limit of the EMA is supplied based on at least the design rate limit and the fault-based rate limit. | 01-28-2010 |
20100071452 | ELECTROMECHANICAL ACTUATOR TEST APPARATUS - An electromechanical actuator test system includes an inertia simulator, a first load actuator, a second load actuator, and a test system control. The inertia simulator simulates the inertia of at least a portion of a system that is moved by a test actuator. The first load actuator supplies a first load to the inertia simulator to simulate at least one or more dynamic system loads, and the second load actuator supplies a second load to the inertia simulator to simulate at least one or more steady-state system loads. The test system control supplies the first actuator commands and the second actuator commands. | 03-25-2010 |
20100072934 | FAULT-TOLERANT CONTROL SYSTEM - A fault-tolerant position feedback filter may be used in an actuation control system to limit the authority of a first position signal, should the first position signal become erroneous, and thereby prevent a postulated runaway condition of an acuator. The filter includes a difference function, a limited integrator, and a summer The difference function is coupled to receive a first position signal and a combined position error signal and is operable to supply a first position error signal representative of a mathematical difference between the first position signal and the combined position signal. The limited integrator is coupled to receive the first position error signal and operable to supply an integrated position error signal that is limited in magnitude to a predetermined limit. The summer is coupled to receive the integrated position error signal and a second position signal and is operable to supply the combined position error signal. The combined position error signal is representative of a mathematical sum of the integrated position error signal and the second position signal. | 03-25-2010 |
