Problems solved by technology

However, due to the measurement noise in the position signal, the speed signal obtained after differentiation often amplifies the measurement noise, making the signal unsatisfactory or even unusable
If the filter is used to filter the position signal first, the signal will be delayed, so that the collected position signal is not a real-time signal
Therefore, the traditional adaptive robust control method has great engineering limitations

Embodiment

[0117] In order to assess the performance of the designed controller, the following parameters are taken in the simulation to model the controlled launch platform:

[0118] Inertia load parameter J=0.0138kg·m 2 ; Viscous friction coefficient B = 0.2N m s / rad; Moment amplification factor k u =53.6N·m / V; constant interference d n =0.3N·m; Elevation and azimuth coupling coefficient c 1 =0.14N·m(rad / s),c 2 =0.13N·m(rad / s); the supremum of time-varying interference is δ=0.3N·m; The upper bound of δ 2 =0.3N·m; θ min =[0.0014,-0.0036,-0.0036] T ; θ max =[0.0167,0.0083,0.0083] T ; The position motion equation in pitch direction θ=0.1sin(πt)[1-exp(-0.01t 3 )](rad);

[0119] The desired instruction for a given system is x 1d =sin(πt)[1-exp(-0.01t 3 )] (rad).

Abstract

The invention discloses an adaptive robustness output feedback control method for a controlled emission platform, belonging to the electro mechanical servo control field. The adaptive robustness output feedback control method for the controlled emission platform comprises steps of establishing a mathematic model of the controlled emission platform, designing adaptive robustness controller for outputting the feedback, and performing a test on the stability of the adaptive robustness controller outputting the feedback. The adaptive robustness output feedback control method for the controlled emission platform performs estimation on inter-framework coupling coefficients of the controlled emission platform, effectively compensates the inter-framework coupling interference torque of the controlled emission platform, effectively observes the system velocity quantity by utilizing an high order sliding mode observer, solves the problem that the velocity quantity is not easy to obtain through the traditional ARC control method, and guarantees the good control performance of the controlled emission platform.

Description

technical field [0001] The invention belongs to the technical field of electromechanical servo control, in particular to an adaptive robust output feedback control method of a controlled launching platform. Background technique [0002] The controlled launch platform is widely used in anti-aircraft weapons. It consists of two parts: the azimuth frame and the pitch frame. The mathematical models of the two are basically the same. Therefore, the design and simulation of the controller can be carried out with the azimuth servo system as the object. When the azimuth frame and the pitch frame of the controlled launch platform move at the same time, the coupling disturbance torque will be generated due to the gyro effect, which will have a certain impact on the control performance of the system. [0003] Aiming at the control problem of the controlled launch platform, many methods have been proposed one after another. Among them, adaptive robust control (ARC) has the advantages o...
